Example: https://codepen.io/anon/pen/VpVLMN
OS X, Win 10, Chrome.

How to reproduce: run example by link above and wait some time(10-30min). While wait open a Chrome's task manager to look how many memory and cpu browser tab with example takes.

It's not usual memory leaks, it is a memory rage. Default, minimal memory is ~150Mb. Then it grows up to 170 by few seconds, then drops to default, after garbage collector have done it's job. Max memory level grows too, I have seen tab takes more than 1Gb (comment out marker and colors in example to get 1Gb fast).

When job for GB is becoming bigger, it takes more CPU, up to 100% on my mac.

It's not a problem when you need to show charts just for few minutes, nobody notice. But for dashboards it's crutical bug.

If something isn't clear, ask me.
