Bulk text compatibility with Bokeh > 3.0.0.

[anastazie]

Hello,
thank you for the wonderful tool!
I tried to edit it a bit and found that for bulk text compatibility with Bokeh > 3.0.0. can be achieved by changing size parameter in scatter to radius.

Example:

circle_kwargs = {
            "x": "x",
            "y": "y",
            "radius": 0.1,
            "source": source_orig,
            "alpha": "alpha",
        }
