This is excellent Leonel!

I���ve tried, but I could not make the visualization work. Apparently you are using a rather old version of Roassal2. I suggest you to update it to the last version of Roassal2.

Cheers,

Hi Max,

Thanks !

The input is a CSV file which contains a grid with city names and latency.

Surely you can zoom-in at city level. However, the map only contains information of the cities that come in the dataset (is not Bern).

Best regards,

Leonel

Very cool.

- Do you parse data from a file? If so, what format does that file need to be in?

- Is the map zoomable to city level (to see connections between Bern and Z��rich for instance)?

Cheers,

Max

Hi All,

I have been working on a visualisation of latency on a network. I found an interesting dataset with latency information of 140 cities around the world.

In the visualisation I show different metrics regarding latency such as from each city which other has the best/worst latency; cities that geographically are close but have high latency; far cities that have low latency; and average latency for each city.

When visualising the worst latency for each city I found that, for this network (at least), Valencia and in a minor extent Nairobi represent the worst endpoint for connections (in terms of latency). Also in the visualisation of far cities with low latency, Newmarket in Canada and Toledo in Spain concentrate the best endpoint for connections coming from Europe and North-America respectively.  

Here a couple of screenshots:
