Reasons to choose canvas?

[wirekang]

Hi, we are considering to migrate to elkjs from dagre. I saw your comment(https://github.com/kieler/elkjs/issues/141#issuecomment-1418664010), this is great demonstration for us. I'm wondering why did you choose the canvas for rendering rather than svg? Since we need to support animations in our graph, svg is proper choice for us due to ease of css-transition. But I want to know are there any limitation that blocking svg or advantages when using canvas. Thank you!
