Document how to set initial spec

[MarcSkovMadsen]

I would like to set the initial spec. The docs says

I do not understand how to use this and cannot find any examples. Please provide.

I would like to be able to use it to finalize the PR https://github.com/panel-extensions/panel-graphic-walker/pull/27.

Solution

My spec was from exporting the current chart. It was a dict in Python. I have to provide it as an Array in React:

<GraphicWalker
...
chart=[spec]
/>

This was not very clear for two reasons

• chart is not in the API props docs: https://github.com/Kanaries/graphic-walker#props
• the legacy spec confused me. It told me to try to use storeRef - which is not documented either.

What helped me was chart usage in https://graphic-walker.kanaries.net/examples/Graphic_Walker_In_a_Modal and chatGPT.
