Isolario stability analysis

This sankey diagram allows to analyse the stability of the graph partitioning technique used for displaying Isolario data.

Blue bars represent graph partitions and encode the amount of ASes they contain. Bars are placed in rows that represent days. Hence, each row summarizes the status of the ASes in a specific day. Links show the amount of ASes moving from one partition to another in two subsequent days.

The graph partitioning technique seems to be quite stable since:

• the amount of partitions is almost equal to 6 except for some cases in which it is 7;
• the overall amount of ASes slightly changes from one day to another;
• no significant flow emerges from one day to another.

(The data set represented covers a time period of 6 months, from March 1 to September 16)
