Canadian province map, bubbles

CDP Data Visualization Map visual enables you to show measurements, as bubbles, over a map of Canadian Provinces and Territories. Bubble maps display up to two measurements simultaneously: as the color of the bubble, and as the relative size of the bubble.

A map of Canada shows a comparison of population among Canadian Provinces and Territories.

The following steps demonstrate how to create a new map of Canada, with population plotted as bubbles, by province. We are using the dataset Canadian Census, constructed from the files canada_census_population_dwellings.csv and ca-postal-codes.csv, and joined of the fields fsa and Postal Code, respectively. See Canadian census. Also, see Adding data and Creating datasets.
