The number of colors to use on the map. A value of 0 uses 
a divergent scale (useful for visualizing negative and positive numbers), A 
value of 1 uses a continuous scale (useful for visualizing outliers), and a 
value in [2, 9] will use that many quantiles.

num_colors

An optional vector of tracts to zoom in on. Elements of this vector must exactly 
match the names of tracts as they appear in the "region" column of the object returned from "get_tract_map".

tract_zoom

An optional vector of county FIPS codes to zoom in on. Elements of this 
vector must exactly match the names of counties as they appear in the "county.fips.numeric" column 
of the object returned from "get_tract_map".

If true, render the choropleth over a reference map from Google Maps.

reference_map

Create a choropleth of Census Tracts in a particular state.

Choropleths are thematic maps where geographic regions, such as
states, are colored according to some metric, such as the number of people
who live in that state. This package simplifies this process by 1.
Providing ready-made functions for creating choropleths of common maps. 2.
Providing data and API connections to interesting data sources for making
choropleths. 3. Providing a framework for creating choropleths from
arbitrary shapefiles. 4. Overlaying those maps over reference maps from
Google Maps.

tract_choropleth: Create a choropleth of Census Tracts in a particular state.
