The `ChoroplethViz` object handles the creation of a choropleth map and inherits from the `MapViz` class. It applies a thematic map style to polygon features with color shading in proportion to the intensity of the data being displayed. Choropleth polygons can be initialized with geojson source or vector source styled using the data-join technique.

### Params
**ChoroplethViz**(_data, color_property=None, color_stops=None, color_default='grey', color_function_type='interpolate', line_color='white', line_stroke='solid', line_width=1, height_property=None, height_stops=None, height_default=0.0, height_function_type='interpolate', \*args, \*\*kwargs_)
