I've been inactive for the last few days, because I was setting up a server in order to make all my tests. As it is the first time I do this, I've met a bunch of (usually stupid) problems, but it's now almost entirely configured! I hope I'll soon be able to provide a web visualization for the k-means algorithm, but it will probably be a simple png at first. It will allow you to test my work without having to download or install anything.
