D3.js: Canvas vs SVG

What are the main differences between using Canvas and SVG in D3.js?

Canvas is a bitmap-based rendering method, while SVG is vector-based. Canvas is better for performance with many objects, while SVG is more suitable for interactivity and accessibility.

When should I choose Canvas over SVG?

Choose Canvas when you need to render a large number of objects quickly, like in games or real-time visualizations. It's more efficient for complex scenes.

Can I mix both Canvas and SVG in a D3.js project?

Yes, you can mix both! Use SVG for static elements and interactivity, and Canvas for dynamic, high-performance rendering.

What are some performance considerations for each?

For Canvas, consider the redraw performance as it clears and redraws the entire scene. For SVG, be mindful of the DOM size, as too many elements can slow down performance.
