Power Map is a feature available in recent release of Microsoft Excel providing easy to use visualization of data in geographical form as well as temporal animation.
In a sample usage to understand where the readers of this blog are from this year, the WordPress stats data from 2016 are imported into Excel Power Map. WordPress already offered graphical presentation of visitor origin in a nice world map. For animating the data through a whole year by month, Excel Power Map is a nice and easy to use tool with just a little bit more effort to create such animation.
The statistic page should be familiar to all WordPress user. Download the data for each month as CSV and store on local drive.
Now prepare the data by consolidating them all in a single Excel worksheet. I used the good ole awk as the source files are in plain text CSV to save some copy and paste efforts. For the animation to work, a new column indicating the time of data (e.g. data for USA in January 2016) has to be added for the Power Map to handle temporal attribute, and this column can not be in formula form.
When the source data are ready, select the whole region and click the 3D Map button under the Insert menu.
Now the Power Map UI will be displayed. A globe map will be displayed by default but since I preferred a flat map form instead of 3D so I clicked on the Flat Map button.
The Power Map user interface works pretty much like a pivot table. You drop the dimension on the pre-defined attribute settings pane on the right hand side to tell Power Map how you would like the map to present your data. To create animation, just drag the date column to the “Time” section as the attribute and Power Map will be able to render accordingly.
Now that everything is ready, the animation play nicely and Power Map will also be able to create the animation file.
