How to Install Google Charts on a Website
To install Google Charts on your website, follow these steps:
Step 1: Include the Google Charts Loader
Add the following script tag in the <head> section of your HTML document to load the Google Charts library:
<script src="https://www.gstatic.com/charts/loader.js"></script>
Step 2: Load the Required Chart Packages
After including the loader, you need to specify which chart packages you want to use. This can also be done in a <script> tag, either in the <head> or just before the closing </body> tag. Here’s an example of loading the core chart package:
<script>
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
</script>
Step 3: Create a JavaScript Function to Draw the Chart
Define a function that will create and draw your chart. This function should be called after the chart packages have been loaded. Here’s an example of a simple pie chart:
<script>
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Element', 'Percentage'],
['Nitrogen', 0.78],
['Oxygen', 0.21],
['Other', 0.01]
]);
var options = {
title: 'Composition of Earth\'s Atmosphere',
width: 550,
height: 400
};
var chart = new google.visualization.PieChart(document.getElementById('myPieChart'));
chart.draw(data, options);
}
</script>
Step 4: Add a Container for the Chart
In your HTML body, create a <div> element where the chart will be rendered. Make sure to give it an id that matches the one used in your JavaScript function:
<div id="myPieChart"></div>
Complete Example
Here’s how everything comes together in a simple HTML document:
<!DOCTYPE html>
<html>
<head>
<script src="https://www.gstatic.com/charts/loader.js"></script>
<script>
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Element', 'Percentage'],
['Nitrogen', 0.78],
['Oxygen', 0.21],
['Other', 0.01]
]);
var options = {
title: 'Composition of Earth\'s Atmosphere',
width: 550,
height: 400
};
var chart = new google.visualization.PieChart(document.getElementById('myPieChart'));
chart.draw(data, options);
}
</script>
</head>
<body>
<h1>My Pie Chart</h1>
<div id="myPieChart"></div>
</body>

Customizing Google Charts
Appearance Customization
Changing Colors and Themes
In the realm of visual storytelling, color is king. Picture Google Charts as a painter’s palette, offering chart customization to match your canvas’s mood.
Are you in the mood for vibrant reds or tranquil blues?
Simply tweak the color codes in your script. With predefined themes or custom palettes, chart aesthetics transform, whispering soft tales or shouting bold headlines.
Adjusting Chart Size and Dimensions
Size matters. Whether you’re drawing a massive wall-sized mural or crafting an intimate postcard, your charts must scale to fit.
Adjust the width and height attributes in your HTML or JavaScript visualization platform—let your data breathe or compress. It’s almost like fitting a bespoke suit; snug or loose, always just right.
Modifying Fonts and Labels
Words matter. Choose a font that sings or speaks. That elegant Arial or that bold Verdana? Labels, titles, and legends need to align not just with each other but with your data’s voice.
A subtle font or a loud typeface can turn numbers into a narrative that dances across the dashboard tools of data visualization.
Data Interaction
Adding Tooltips
Hover, pause, and reveal. Tooltips are the secret whispers of your charts, offering deep insights with a mere touch.
Hover over data points and watch as tooltips emerge, tiny windows of enlightenment, ready to reveal secrets in their dynamic charts.
They are the pop-up books of data visualization, inviting interaction with every pointer pause.
Enabling Legend Interaction
Imagine a dance floor where clicking elements changes the rhythm. Enable legend interaction within your charts; let users toggle and twirl datasets in and out of view.
This isn’t just a chart library; it’s a stage for interactive experience, where users become conductors of their data symphony.
Implementing Zoom and Scroll
Sometimes, seeing the big picture isn’t enough; we need to zoom into the heart of the story.
Implement zoom and scroll capabilities—allow users to glide through data, magnifying sections with a flick of the finger or a scroll of the mouse.
Responsive designs invite exploration, allowing stories to stretch and contract with ease.
Responsive Design
Making Charts Responsive
In a world where screens shrink and stretch, charts must be nimble. Create responsive design so charts transition elegantly from desktop vistas to pocket-sized frames.
Web-based visualization demands elasticity, stretching to greet any device as gracefully as a cat stretches into sunbeams.

The web doesn’t sit still; it hops from laptop to tablet to phone. Design your charts with media queries, letting them metamorphose as seamlessly as seasons shift.
Your data’s beauty should remain intact whether viewed through a panoramic lens or a peephole.
Mobile-Friendly Chart Designs
In a fast-paced, fingertip-driven world, mobile-friendly charts are more than a luxury—they’re a necessity. Simplify interactions without sacrificing depth, ensuring tap targets are just right.
Let your charts become business intelligence tools, agile and informative, offering insights as crisp on mobile as on any grand screen.
Integrating Google Charts with Web Applications
Using Google Charts with JavaScript Frameworks
Integration with React
To integrate Google Charts with React, follow these steps:
Install the required packages:
npm install react-google-charts
This will install the react-google-charts package, which is a thin, typed wrapper for Google Charts that makes it easy to use in React applications.
Import the necessary components:
import { Chart } from "react-google-charts";
The Chart component from react-google-charts is used to render the charts in your React components.
Prepare your chart data:
export const data = [
["Task", "Hours per Day"],
["Work", 11],
["Eat", 2],
["Commute", 2],
["Watch TV", 2],
["Sleep", 7],
];
export const options = {
title: "My Daily Activities",
};
The data array represents the data to be displayed in the chart, and the options object contains the chart configuration options.
Render the chart in your component:
const MyChart = () => {
return (
<Chart
chartType="PieChart"
data={data}
options={options}
width={"100%"}
height={"400px"}
/>
);
};
The Chart component accepts several props, such as chartType, data, options, width, and height, to customize the chart’s appearance and behavior.
Using Google Charts with Hooks
You can use Google Charts with React Hooks by following these steps:
Create a custom hook to handle the Google Charts initialization:
import { useEffect, useState } from "react";
const useGoogleCharts = () => {
const [google, setGoogle] = useState(null);
useEffect(() => {
const script = document.createElement("script");
script.src = "https://www.gstatic.com/charts/loader.js";
script.onload = () => {
google.charts.load("current", { packages: ["corechart"] });
google.charts.setOnLoadCallback(() => setGoogle(google.charts));
};
document.body.appendChild(script);
}, []);
return google;
};
This hook loads the Google Charts library and sets the google state when the library is ready.
Use the custom hook in your component:
import { useGoogleCharts } from "./useGoogleCharts";
const MyChart = () => {
const google = useGoogleCharts();
return (
<>
{google && (
<Chart
chartType="PieChart"
data={data}
options={options}
width={"100%"}
height={"400px"}
google={google}
/>
)}
</>
);
};
The Chart component now receives the google prop, which is passed down from the custom hook.
Handling Dynamic Data
To update the chart with dynamic data, you can use the useEffect hook to monitor changes in the data and re-render the chart accordingly:
import { useEffect } from "react";
const MyChart = ({ data }) => {
const google = useGoogleCharts();
useEffect(() => {
if (google && chartRef.current) {
const chart = new google.visualization.PieChart(chartRef.current);
chart.draw(google.visualization.arrayToDataTable(data), options);
}
}, [google, data]);
const chartRef = useRef(null);
return (
<div ref={chartRef}>
{google && (
<Chart
chartType="PieChart"
data={data}
options={options}
width={"100%"}
height={"400px"}
google={google}
/>
)}
</div>
);
};
In this example, the useEffect hook is used to draw the chart whenever the data or google prop changes. The chartRef is used to reference the chart container element.
Integration with Angular
To integrate Google Charts with Angular, you can use the angular-google-charts library, which serves as a wrapper for the Google Charts library. Here are the steps to set it up in your Angular application:
Step 1: Install the Library
First, install the angular-google-charts package using npm:
npm install angular-google-charts
Step 2: Import the Module
Next, import the GoogleChartsModule in your application’s main module file, typically app.module.ts:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { GoogleChartsModule } from 'angular-google-charts';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
GoogleChartsModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Step 3: Create a Chart Component
In your component (e.g., app.component.ts), define the chart’s data, type, and options:
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'Google Chart Example';
type = 'PieChart'; // Specify the chart type
data = [
['Task', 'Hours per Day'],
['Work', 11],
['Eat', 2],
['Commute', 2],
['Watch TV', 2],
['Sleep', 7]
];
columnNames = ['Task', 'Hours per Day'];
options = {
title: 'My Daily Activities',
pieHole: 0.4,
};
}
Step 4: Add Chart to Template
In your component’s HTML file (e.g., app.component.html), add the Google Chart component:
<google-chart [title]="title" [type]="type" [data]="data" [columnNames]="columnNames" [options]="options" [width]="400" [height]="300"> </google-chart>
Additional Configuration
You can customize your charts further by modifying the options object, which allows you to set various properties such as colors, tooltips, and chart titles.
The library supports a variety of chart types, including bar charts, line charts, and more, which you can specify by changing the type property in your component.
Integration with Vue.js
Here’s how to integrate Google Charts with Vue.js:
Install the vue-google-charts package
First, install the vue-google-charts package in your Vue.js project:
npm install vue-google-charts
This package provides a reactive wrapper for the Google Charts library, allowing you to easily use charts in your Vue components without having to load the Google Charts library manually.
Import and register the GChart component
In your Vue component, import the GChart component from vue-google-charts:
<script>
import { GChart } from 'vue-google-charts'
export default {
components: {
GChart
},
// ...
}
</script>
You can either register it locally in your component or globally as a plugin.
Use the GChart component in your template
In your component’s template, use the <GChart> component to render a chart. Specify the chart type using the type prop, the data using data, and any options using options:
<template> <div> <GChart type="ColumnChart" :data="chartData" :options="chartOptions" /> </div> </template>
The chartData and chartOptions are defined in your component’s data:
export default {
data() {
return {
chartData: [
['Year', 'Sales', 'Expenses', 'Profit'],
['2014', 1000, 400, 200],
['2015', 1170, 460, 250],
['2016', 660, 1120, 300],
['2017', 1030, 540, 350]
],
chartOptions: {
chart: {
title: 'Company Performance',
subtitle: 'Sales, Expenses, and Profit: 2014-2017'
}
}
}
}
}
The chartData is automatically processed using google.visualization.arrayToDataTable.
Load additional packages (optional)
If you need to use additional Google Charts packages, you can specify them using the settings prop:
<GChart
:settings="{ packages: ['corechart', 'table', 'map'] }"
type="Map"
:data="chartData"
:options="chartOptions"
/>
corechart, table, and map packages.Connecting to Live Data Sources
