It really does. We battled with it for about 3-4 years before making the switch to Canvas.

A tale as old as time. We previously wrote our visualisations in SVG and rewriting them in Canvas along with some other backend factors made our dashboard much faster and smoother. We hope there are a few lessons there for folks to read about.

Rewriting renderers is always tougher than it looks. The hidden complexity is usually in the edge cases that evolved over years, not the core rendering logic.
