Ask HN: Comparison of all ML algos – does anyone remember the page URL?

There was a cool page linked on HackerNews several months ago. It had grid of icons demonstrating all ML algos and I think where/when can one use one of them. I forgot to bookmark it. Can anyone shed some light on it?

It looked similar to sklearn user guide, but had smaller icons..

I owe you pizza if you help me :)
