# ## Category widget
# 
# Category widgets group features from string columns into aggregated categories based on their occurence in your current map view and displayed with their associated counts. You can filter on a particular category by selecting it and by default, as you zoom or pan the map, the values in the widget update to the current viewport.
# 
# To see available parameters run `help(category_widget)`.
# 
# In the example below, the category widget summarizes the types of collisions in Seattle.
