A way to start this project (using Dendron as a knowledge base) and garner support is:
0. Choose a language (Raw HTML/CSS/JS, Python, etc.) or framework (VueJS, Svelte, etc.)
1. Test and document nuances with all the Chart Site API's (<---Dendron)
2. Embed a .drawio diagram explaining what you think the architecture would look like (<---Dendron)
3. Create a GitHub repository with a README.md file with the diagram embedded and a short write up (user profile, business case, etc.)
4. Create a Discord server
These first steps create a place where developers could actually help and you've established a common sheet of music for collaboration
