Here is the current diff (via https://plotly.com/javascript/reference/#layout) for layout objects and properties that are supported by this library (on a high abstraction level, theoretically we already support everything via DynObj):

You want to help? Here's a quick guide on how to implement a layout object:

• Take a look at this commit, which implements all the steps below: 18b5698
• ideally leave a comment here so we dont have multiple ppl doing the same thing
• go to the figure reference for your layout object
• implement the object via the init/style pattern
• when possible abstract things like enums as StyleParam.
• where applicable, add a Chart.with... function to ChartExtensions.fs that applies the object styles to a given Chart layout.

Thanks ❤️
