Offload chart initalization to web workers

Has it been explored if CPU-intensive tasks like chart initialization can be offloaded to web worker threads?

For example, when I initialize around 20 charts at the same time, I observe a 5 second freeze of the current browser window in Firefox. During this period, I don't see anything drawn to the DOM, so I assume the code that runs could potentially be offloaded to a worker thread, which could then communicate the resulting SVG to the main thread.

I think a change like this could be a great win in terms of user experience.

Also, have a related StackOverflow question.

该 issue 未指定任何文件、测试或入口点。首先在 Firefox 中对图表初始化进行性能分析，并跟踪创建多个图表时执行的工作。完成的要求是确定一种基于 worker 的初始化方案，并有证据表明浏览器冻结现象得到了缓解。
