# Chart.js

• Chart.js is a community maintained open-source library (it’s available on GitHub) that helps you easily visualize data using JavaScript. It’s similar to Chartist and Google Charts. It supports 8 different chart types (including bars, lines, & pies), and they’re all responsive. In other words, you set up your chart once, and Chart.js will do the heavy-lifting for you and make sure that it’s always legible (for example by removing some uncritical details if the chart gets smaller).

this is what you need to do to draw a chart with Chart.js:

• Define where on your page to draw the graph.
• Define what type of graph you want to draw.
• Supply Chart.js with data, labels, and other options.
