Hello! I'm pleased to announce the very first version of hierarchical-clustering-diagrams [1]. This library builds upon Brent Yorgey's great diagrams library to draw diagrams of dendrograms. You can see an example diagram at [2]. This library has already been tested with a Real World Big Data dendrogram and has a pretty nice performance. It generates a 20,000 x 5,000 px PNG in less than 15s on a 2 years-old Core 2 laptop. Note that while this library depends on the hierarchical-clustering library [3], nothing stops you from using any other method of creating your dendrogram. You only need to convert your dendrogram to the data type provided by hierarchical-clustering, which should be straightforward. However, I'd love to hear if someone finds both libraries useful =). Cheers, =D [1] http://hackage.haskell.org/package/hierarchical-clustering-diagrams [2] https://patch-tag.com/r/felipe/hierarchical-clustering-diagrams/snapshot/cur...
