Create a chloropleth map from geojson

I am trying to make a chloropleth map using a geojson. I was able to get the shapes on to the map but I am not sure how to scale the values.

The values I am trying to scale are within the geojson property key.

I tried using the florida county level example as well as the documented chloropleth map but was unsuccessful.

Any suggestions?

@tcurran4589 In this Jupyter Notebook https://plot.ly/~empet/14692 you can find a mapbox choropleth defined by data from a topojson file, transformed to a geojson dict. Moreover there is a function that associates to a value val, in an interval [vmin, vmax],
the corresponding color in a Plotly colorscale.
