You can also vibe-code your widget if you want! You are not restricted to use the built-in ones. Just copy the "Canvas Widget Guide" you find under "Left Sidebar > Create > Smart Widget > Tutorial" and copy that article in ChatGPT or Claude while describing what your widget should display.
Then paste the code to "Create > Smart Widget > Edit the Code" in the Widget Details. (this flow should be more intuitive...)
You are able to send JSON data to your widget via an API.
It's all just canvas and old Javascript code!
