python figure factory Create_choropleth

Continuing the discussion from Create_choropleth:

Hi Team , I was able to use county choropleth map created using create_choropleth function ( Usa county choropleth maps in Python ).

When we hover over county it shows data using County , State , FIPS and Value tag.
Is there a way to customized this text so that it display only county name and another tag attribute with value. For example :- desired output - County : Westmoreland , Attribute1 : Value1 , Attribute 2 ;Value2.

For future reference, see discussion at plotly/plotly.py#1020
