This is a chart of my experience in programming languages and some other languages I decided are worth mentioning here. It's powered by some JavaScript I wrote and the canvas element.
Each line's length represents the time I've been using the language in question. Their thickness and proximity to trunk represents how familiar I'm with the language's workings, in relation to the others. If a line stops before the right side of the chart, it means I haven't used that language for a while.
Note: I haven't kept track of when I picked up which language. This is only based on what I remember.
