Javascript front end

[partofthething]

Right now, the system uses matplotlib on the backend to make PNG images to be shown in the browser. This has some disadvantages in backend speed and theme matching.

A version of this with a javascript front-end might be really awesome.

Plotly js has some pretty good examples along these lines that we can probably work from easily.

I just need to figure out the structure of getting a lovelace card into a custom component repo and then get the data to it.

A little progress. I have a dummy plot plotting with dummy data to a degree in here. It's not perfect, but it wasn't easy to get here for me!

More work:

• Find a suitable plot library and get it to work with lovelace
• Make a home assistant entity with data from skyfield to send to the frontend for rendering
• Update the custom card js to use actual data from the entity
• Polish the heck out of the js front end.
