Topological data analysis through the web

It is often the case that one of the crucial factors underpinning wide scale adoption of any computational procedure is the availability of easy to use packages containing that procedure, usable by people who have only a passing familiarity with the innards.

Topological data analysis is one such toolbox, the inner workings of which have often seemed too hard to penetrate for anyone but the most mathematically well trained scientists (a very small population, indeed). Yet, the tool has many appealing characteristics, given how centrally relevant its core questions are to hierarchical representations, multi-scale modelling and so on.

In this context, it is nice to see this web based interface for persistent homology calculations, a key tool in the TDA toolbox:
