In the interactive, there are different input fields for number of clusters and number of centroids. Isn't the number of centroids supposed to be equal to the number of clusters? Can they be different?

Hi!
First of all, thank you very much for taking the time to create this, it really helps to understand the algorithm! :)

Now I might be wrong because I'm no expert, but it seems to me that the centroids that are displayed at the very beginning are not the ones that the algorithm works with. Here's an example:

Steps I took:

1. Open the page

2. Set the Data slider to about 90% (closer to random)

   

3. Click 'Find closest centroid'

   

('Update centroid' now moves the centroids to the centres of the coloured regions)

Current example site is broken since it auto-upgrades to HTTPS but all of the CSS and scripts are forced to be over HTTP. Mixed content is not allowed in any modern browser. Changing the src and similar attributes to start with just // (instead of https:// or http://) which will make it protocol relative.
