Visio Map of the World Update

My earlier post about the world in Visio shapes, see http://blog.bvisual.net/2013/08/16/visio-map-of-the-world/ , has been one of my most popular, and a reader recently asked about changing the colour of countries by data not in my original worksheet, and another asked about adding labelled dots.

Well, at first, I thought it would be quite simple to add more Data Graphics with the Color By Value that I already had, but then I realised that I needed to adjust some of the shapes that I had created from SVG in my previous article.

The problem is that some of the country shapes which were converted from SVG have geometry at the top group level. This means that any Data Graphic items, other than Color By Value, are actually sub-shapes of the group and will be hidden by the country shape itself. That is probably why the Data Graphics task, on the selected Afghanistan shape below, sent the AF label over to the right of it, whereas all the group shapes with all their geometry in sub-shapes, such as the AE (United Arab Emirates) shape, placed the label in its centre.

Therefore, I wrote some VBA code to move the geometry out of the top-level group shape into a new sub-shape, which then allowed the Data Graphic task to position the graphic items over the group shape. Notice that the af shape in the Drawing Explorer below now has a subshape, also called af.

I have listed the code below, and it can be run against the earlier version of the world map that I posted.

End Sub

So, now that I have a map that can utilise more than just Color By Value Data Graphics, I added extra columns of data from a second worksheet to the existing country Shape Data from my earlier post.

One of these extra columns contains the estimated population, so I changed the Data Graphics to display the population as Color By Value, and the ISO2 code as a Circle callout, with a Value Length = 2.

This results in a rather nice world display of population size per country.

To complete the map, I added a legend using the DATA ribbon button, but was not thrilled with the default appearance, so I edited it, just by selecting the elements and overtyping.
