Google Charts has a wide variety of charts and operates with both SVG and HTML5 technology to be highly compatible. It is free to use and is a great library to launch charting. It doesn't offer as much customizability as some other charting libraries, but is a great solution.
Vue.js is a progressive JavaScript framework used for building user interfaces and single-page applications (SPAs). It was created by Evan You and is designed to be incrementally adoptable. The core library focuses on the view layer only, making it easy to pick up and integrate with other libraries or existing projects. Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries. It has a virtual DOM for faster and more efficient manipulation, composable components, and a relatively low learning curve. It is great for ease-of-use, performance, and overall developer experience.
To integrate Google Charts with Vue.js, we'll start by creating a Vue component that loads a Google Chart. The example will showcase a basic bar chart visualization.
- Ensure you have Vue.js installed in your project. If not, you can add it by using a CDN or through npm:
<!-- Include Vue via CDN for demonstration -->
<script src="https://cdn.jsdelivr.net/npm/vue@2"></script>
- We'll also load the Google Charts library using its loader:
<!-- Load Google Charts -->
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
In your HTML file, add a div element that will serve as the container for the Google Chart. Also, ensure Vue is integrated into your project.
<div id="app">
<google-chart></google-chart>
</div>
Now, let's create a Vue component named `google-chart` that will render the Google Chart.
<script>
// Define the google-chart component
Vue.component('google-chart', {
template: '<div id="chart_div" style="width: 900px; height: 500px;"></div>',
mounted() {
// Load the Visualization API and the corechart package.
google.charts.load('current', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.charts.setOnLoadCallback(this.drawChart);
},
methods: {
drawChart() {
// Standard Google Charts setup
var data = google.visualization.arrayToDataTable([
['Element', 'Density', { role: 'style' }],
['Copper', 8.94, '#b87333'],
['Silver', 10.49, 'silver'],
['Gold', 19.30, 'gold'],
['Platinum', 21.45, 'color: #e5e4e2']
]);
var options = {
title: "Density of Precious Metals, in g/cm^3",
bar: {groupWidth: "95%"},
legend: { position: "none" },
};
// Instantiate and draw the chart
var chart = new google.visualization.BarChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
}
});
// Create the main Vue instance
new Vue({
el: '#app'
});
</script>
This code defines a Vue component that utilizes the Google Charts library to render a bar chart inside the `#chart_div` element. The component is then used within a Vue instance bound to the `#app` div.
Thus, by following these steps and utilizing the given code example, you can easily integrate and use Google Charts in a Vue.js application to display data visually.
