I'm trying to use a toolbox created by someone at Esri to help with the creation of bivariate choropleth maps.
I'm not sure, though, how to import the toolbox and the other files so that I can use them in ArcGIS Desktop.
I downloaded and registered the renderer just fine. The author gives the link to the zip file with the geoprocessing tool but does not give directions on how to add the tool to ArcMap.
Here is link to the blog where I found out about this method:
