Use a circle that cannot be stretched using onMouseMove
Modify the x and y parameters so that a mouse click will place center

Hi @andfanilo,

Here is the implementation I mentioned in my comment on this issue. I don't think I have the rights to link the issue to this PR directly, feel free to handle that on your side.

Let me know what you think!

andfanilo commented 2 years ago

Good thinking about editing the README.md. You'll also need to edit the docstring in __init__.py to add the point choice.
If you feel comfortable enough with doing this, is there a way to put the radius of the circle as argument of the Python call and have it propagated to the radius of the point? Otherwise you can create an issue for it and we can go back to this afterwards

Hey @andfanilo, I was able to implement the additional radius parameter on st_canvas and complete the downstream pipeline. I added a slider to test it out in the app.py example present in theREADME.md. Let me know what you think!

This LGTM! Let me merge and play with it too :)
