In CDP Data Visualization Map visual, you can visualize measurements on a map of DMA
regions. A DMA map shows various measurements plotted relative to Nielsen Designated Market Area
Regions.
In this example, the DMA TV Home Viewing is used, which is built on the
dma-tv-home-viewing.csv datafile.
Start a new visual based on the DMA TV Home Viewing dataset.
For instructions, see Creating a visual.
In the VISUALS menu, find and click
Map.
The shelves of the visual changed. They are now Geo,
Color, Size, Drill,
Tooltips, X Trellis, Y
Trellis, and Filters. The only mandatory shelf for
map visuals is Geo.
Populate the shelves from the available fields (Dimensions and
Measures) in the DATA menu.
Under Dimensions, select dma and add it to
the Geo shelf.
Under Measures, select homes and add it to
the Color shelf.
Alias the field dma as DMA, and
sum(homes) as Number of Homes.
For instructions, see Alias.
Add the dimension dma_name to the Tooltips
shelf, and then alias it as DMA Name.
Optional: Enable panning and zooming option, as described in Customizing zoom.
Optional: Change the color palette, as described in Change color palette
visuals.
Click REFRESH VISUAL.
The map visual appears. You can move the visual (pan), zoom in and out, and see the
