This Labs visualization is available in classic Fusion Tables.
Fusion Tables map charts let you compare and contrast multiple values at a glance. For example, after the Iowa 2012 caucus, you could compare how each candidate fared in each region and how the regions varied.
To create a map chart:
- Choose Labs > Map charts.
- Select Label. This is a column with unique names for the polygon regions. The names are used on the x-axis in the charts and identify the regions on the map.
- Select Polygons. This must be a column of KML polygon shapes.
- Select one or more Metrics: These are number columns to be the y-axis values in the charts.
Interact with the Map Charts
- Click a region on the map. The region names become the map's legend, and the region's metrics are added to the charts. Click a region again to remove it.
- Each metric displays a chart. You can show/hide each of them.
- Change the sort order: Click on a metric name to sort all charts by that metric. A small triangle appears. Click again to return to the original sort order.
More details:
- Each region name and KML polygon description must be unique.
- You can compare up to a maximum of four regions.
Example: Iowa 2012 Caucus Data
Here's an example:
- Open the Iowa Caucus 2012 table.
- Choose Labs > Map charts.
- Select District Name as the Label. This identifies the Iowa counties.
- Select Shape as the Polygons. This holds the county boundaries in KML.
- Select VoteCountsRomney, VoteCountsSantorum, and VoteCountsGingrich as the Metrics.
To explore,
- Click on 3 or 4 map regions.
- Click on the VoteCountGingrich link to sort according to his vote counts. Then click on Santorum to see how the sequencing of the bars changes.
