What problem does this feature solve?

i was polt a heatmap with a 100*100 matric, it will render slow. Sometimes, i need use resize() instance method, and getDataURL() to download, this will get a uncompleted render plot, like this

What does the proposed API look like?

add resize callback method

Have the same problems, when I want to render around 20_000 items.
Also when I tried filter chart by visual map, rerender also take so slow.
