Latitude and longitude map with bubbles
CDP Data Visualization Map visual supports measurement plots over a geographic map, based on latitude and longitude. Bubble maps display up to two measurements simultaneously: as the color of the bubble, and as the relative size of the bubble.
A geographic coordinate map of the United States, based on degrees of
longitude, shows a comparison of
measurement values across US States.
The following steps extend the work completed in US zipcode map with bubbles,
and demonstrate how to create a map visual on the dataset Income Tax Returns.
It produces maps with bubble marks that correspond to the relative size of the measurement
Before starting this exercise, supplement the Income Tax Returns dataset by
adding data from
into your database, and making a simple joins between
zipcode_lat_long.zipcode. See Data model: joins.
