What is Chart.js?

Chart.js is a free, open-source JavaScript library for data visualization. Across industries, developers use it to create different types of HTML-based charts for both commercial and personal use. For example, a food retailer that wants to display the calorie counts on their online menu could use Chart.js to visualize those data points in a graphical format. Similarly, applications that track the prices of certain products around the web might use Chart.js to display price timelines.

Charting libraries like Chart.js provide a collection of chart types, plugins, and customization types for developers to quickly build interactive data visualizations. Built-in chart configurations offer out-of-the-box charts, with the option to add extras such as annotations and drag-and-drop functionalities.

Whether you want to visualize simple data points or create complex, interactive charts, Chart.js can help you turn data into visual information for websites and mobile applications. With Chart.js, you can create: area charts, bar charts, bubble charts, line graphs, pie charts, polar area charts, radar charts, scatter plots, and mixed-type charts.Footnote 1
