It is nice, but a little misleading. The size of each dot should consistently mean the same range of values regardless of country. As it is, it looks as through Andorra had as many tournaments last year as Netherlands.

Logarithmic scales are usually very misleading, even more when sizes are the subject. Actually I was expecting a dynamic time plot-vs-location... It's extremely messy to get one of these right, but when they are they are great. This is cool nevertheless, but I have the feeling C class tournaments should be disabled by default. I don't know about other countries, but in Spain C class seem to be used for gatherings where 3 people meet, play and one of them knows how to register it in the EGD.

How about a quadratic scale? If you make the radius of the circle equal to the square root of the number of tournaments, then the surface areas of various circles would be directly related to the number of tournaments (as surface area involves squaring the radius again).

France, with 144 tournaments, would have radius of 12, while Andorra would have radius 1, which both seem quite reasonable.

The thing about France is that they started including club results as well, that's why they have that huge bump from around 30 tournaments to over 150. The same is true for some other countries, such as Russia.

if you look at the French tournament list, you will find lots of entries of the form "<CLUBNAME> continuous tournament" and "<CLUBNAME>, round 1", having only one or two rounds. Those are just the results from regular club gatherings, not actual tournaments.

I wonder how the data would look if you added a filter to discard any events with less than 3 rounds, or more than 10, as 99% of those are probably not real tournaments. Similarly, you could add filters on number of players.

I see that none of the tournaments supposedly in Andorra actually took place there

It is nice indeed! Maybe though, somebody ought to contact Aldo to tell him to correct the tournament country code on those events from Andorra.
