Hapstar is the new name for my little bioinformatics project, visualising population structure from differences between genetic sequences. The last few days I’ve done a lot of work on the GUI, allowing you to drag nodes around by hand, zoom in and out and navigate the graph. Also quite a bit of graph theory, validating the input graphs by detecting if they are a single connected component – or contain isolated graphs. It’s already been used to produce figures for an upcoming publication, so hopefully I can show some real examples soon.
