Since we are moving to Vega 5, we need to fix all the deprecated syntax across all projects. @Jdlrobson made a map that allows you to use the old syntax, but in the long run, this is an extra technical debt.
TODO
- Help the community prioritize graphs to fix based on JavaScript error that have been logged
- When enough time has passed OR the majority of graphs have been upgraded, drop the mapSchema coee so that graphs using an outdated schema display an error.
