How to hide the legends for GraduatedCircleViz?

I tried legend=False but it does not work. I wanted to assign the radius and the color of the circles based on two properties, but it leads to a problem that there creates two legends which either overlap each other or overlap the map. How can I fix that?

Reproduce the issue in a Python Jupyter notebook with GraduatedCircleViz, legend=False, and separate radius and color properties. Start by tracing how GraduatedCircleViz creates its legends; done means both legends can be hidden without overlapping each other or the map.
