Treemap and Sunburst Excel2016 charts for Tour De France

#57 Treemap and Sunburst Excel2016 charts for Tour De France

In 2015 Tour de France contracted the company Dimension Data to make the event as high tech as possible. As DD said themselves: 

It has completed its big data analytics and digital delivery platform from which the company will deliver real-time information on individual riders for the first time in the history of professional cycling. This major innovation was made possible by Amaury Sport Organisation (ASO) in partnership with the 22 teams participating in the 2015 Tour de France. Highly accurate data will be collected through the use of live trackers under the saddle of each rider. Dimension Data will then process and analyse the data, and make it available to cycling fans, commentators, broadcasters and the media.

When the Tour de France begins on Saturday, the viewing public around the world will be able to follow all 198 riders in 22 teams real-time, and be able to track the speed at which each cyclist is riding, exactly where he’s positioned in the race in relation to other cyclists, and the distance between each rider - all via a beta live tracking website.

And I think they did an excellent job, and also in this year's edition.
On one of their Twitter-posts:
 I once saw a graphic (data: total % of time a cyclist was leading in the breakaway group) which I didn't know, and which was something which could not be made with Excel (2013), but a bit later, which the launch of Excel-2016, I learnt that this graph was a Treemap, so now supported by Excel, and I tried to reproduce, see e.g. fig.1

fig.1 Treemap chart wit data from teams and cyclists

Besides the Treemap chart, Excel 2016 had another new graph, the Sunburst chart, see fig.2 for an example

Both the Treemap and the Sunburst-chart are for displaying hierarchical data, so e.g. in Tour de France, cyclists are part of a team, so you can compare the teams performances (total times) and breaking it down to the indivual cyclists performances, as done in fig.1. Another possible grouping is cyclists per country as in fig.2, although this is more artificial, so not something which is considered by the Tour de France, while grouping by teams is of course (there is a prize for the best team). 

And if fig.3 you can see the equivalent of fig.2, but now in Treemap format. Maybe this format is handier if you have less space, like e.g. Dimension Data had, where this chart was part of a dashboard with other charts.

And in fig.4 you can see the original Dimension Data Treemap, which in fact did not have any hierarchical data, just data of cyclists. In this chart it is of course the easiest to compare data of 2 riders, e.g. the 2 best riders in the breakaway-group were Roland and Rodriguez (both in left of chart, with same square-size).

For me, the new high-tech dimension (also by using onboard cameras) makes the Tour de France much more interesting to follow, and of course the fact that the Dutch are doing very well in TDF2016 (Tom Dumoulin 2 stage victories and Bouke
Mollema #2 in general ranking).
