To sum it up straight away: First and foremost I am looking for software to create something like this (advanced cluster diagram?) from a data set.

A (very small) sample data set looks like this:

+-----------+-----------+-----------+-----------+-----------+
|           | Cluster 1 | Cluster 2 | Cluster 3 | Cluster 4 |
+-----------+-----------+-----------+-----------+-----------+
| Cluster 1 |         - |         4 |         4 |         1 |
| Cluster 2 |         2 |         - |         2 |         3 |
| Cluster 3 |         3 |         0 |         - |         2 |
| Cluster 4 |         1 |         2 |         0 |         - |
+-----------+-----------+-----------+-----------+-----------+

Depending on the number the cluster would be closer together or further away. The more cluster are close to one cluster, the more inflated it gets.

So on a higher level: I need a software (web app, desktop app, JavaScript library, whatever) to create these types of diagrams from input data I specify.

This is called a network diagram, and you can use (for instance) the free desktop app Gephi or igraph to plot these.

Usually the input data is given either

  • as a nodelist and an edgelist
  • as an adjacency matrix --that's what you mentioned?
  • in other forms

You make these plots by filtering the graphs, and plotting subsets.

I personally would use R and the visNetwork package (which offers a binding to the visJS javascritp library, but this is just my personal preference. Depending on your data, it can quite a be lengthy task until you get what you want.
