Steps to Add Google Charts to Your Webpage
Step 1: Load the Google Charts Library
To start using Google Charts, you need to load the library in your HTML file. Insert the following script tag inside the <head> section of your HTML document:
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>Step 2: Initialize the Google Charts
Next, you will need to create a function to load and set up the chart. Here’s an example for a simple pie chart:
<script type="text/javascript">
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Task', 'Hours per Day'],
['Work', 11],
['Eat', 2],
['Commute', 2],
['Watch TV', 2],
['Sleep', 7]
]);
var options = {
title: 'My Daily Activities'
};
var chart = new google.visualization.PieChart(document.getElementById('piechart'));
chart.draw(data, options);
}
</script>Step 3: Add a Div Element for the Chart
Now, you need to add a <div> element in your HTML where the chart will be displayed. Place this <div> in the <body> section:
<div id="piechart" style="width: 900px; height: 500px;"></div>Step 4: Complete HTML Example
Here’s how your complete HTML file should look:
<!DOCTYPE html>
<html>
<head>
<title>Google Charts Example</title>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Task', 'Hours per Day'],
['Work', 11],
['Eat', 2],
['Commute', 2],
['Watch TV', 2],
['Sleep', 7]
]);
var options = {
title: 'My Daily Activities'
};
var chart = new google.visualization.PieChart(document.getElementById('piechart'));
chart.draw(data, options);
}
</script>
</head>
<body>
<h1>Google Charts Example</h1>
<div id="piechart" style="width: 900px; height: 500px;"></div>
</body>
</html>Step 5: Test Your Chart
Save your HTML file and open it in a web browser. You should see a pie chart representing your daily activities. You can interact with the chart by hovering over the sections to see the details.
Troubleshooting
If the chart does not display:
- Check Your Internet Connection: Google Charts requires an internet connection to load the library.
- Verify Script Loading: Ensure that the script tag for loading Google Charts is correctly included in the
<head>section. - Inspect for JavaScript Errors: Open your browser’s developer tools (F12) to see if there are any errors in the console.
