The size-continuous type draws an unclassed legend based on your data's geometry using either the size (default) or stroke_width property of your visualization.
To view available legend parameters, run help(size_continuous_legend)
In this example, the size continuous legend reads from the size property to draw a size legend with representative symbol sizes and the min and max values labeled.
