[spike] Are SVGs more accessible than PNGs?

[meganesu]

Open Questions:

• Are SVGs more accessible than PNGs?
• Should I be using SVG instead of PNG for the excalidraw diagrams in my blog posts?
• How do I get SVGs to load in my markdown posts?
  • Using the standard Markdown format ![alt](path to svg) doesn't seem to work with my current setup (gatsby-remark-images, gatsby-plugin-sharp, gatsby-transformer-remark).

To use SVGs in Markdown posts, use gatsby-plugin-react-svg
