True Cross Browser Charts And It's Beautiful!


No one like the legacy. But sometimes it matters. That is why we started this project. As we couldn't find a project which supporting legacy browsers, maintained reliably, and free for commercial use.

You can see the charts in IE8 exactly as it looks in Chrome. Of course, there are other projects that support the legacy browser. However, They may function limited, look different or require polyfill that affects performance badly. The TOAST UI Chart guarantees identical look on all browsers. And it draws using what browsers have natively(SVG + RVML). So, It requires no polyfill and draws faster.

The TOAST UI Chart will continue to support legacy browsers as MIT license No wonder the other open source charts stop supporting legacy browsers. It's hard to find open-source charts which reliably maintained. And some of the decent charts ask commercial licenses. The TOAST UI Chart has over 50 releases since Jun. 2015 under MIT License. The TOAST UI Chart is the answer if you have same requirements as us.


The TOAST UI Chart is an open source JavaScript library that can be used in legacy browsers including IE8. It is intuitive and easy to apply without any other learning. If you like, you can change the chart in detail using many options and custom themes.

The TOAST UI Chart can be used by creating an instance with the constructor function. To get the constructor function, you should import the module using one of the following three ways depending on your environment.

var chart = tui.chart; /* namespace */
var chart = require('tui-chart'); /* CommonJS in Node.js */
import {chart} from 'tui-chart'; /* ES6 in Node.js */

Factory function needs three paramters: container, data, options

  • Container: Wrapper HTMLElements that will contain charts as a child
  • data: numeric data need to make charts
  • options: functional options like legend aligment or tooltip visiblities
var container = document.getElementById('chart-area');
var data = {

var options = {
    chart: {width: 700, height: 400}

chart.barChart(container, data, options);
