That looks awesome. I'm looking forward to learning more JavaScript. I've only covered the basics so far, but it seems to be where a lot of exciting stuff happens in development world. What sort of data are you visualizing? For this site I'm using the alpha of Bootstrap v4. The module of the course I'm doing is currently on Bootstrap, so it seemed a good excuse to cement some of that knowledge. Funnily enough, until about 5 days ago I didn't really know what a framework was. I coded the first version of the site entirely from scratch, so learning about the power of frameworks was a very welcome revelation. So much so that I didn't mind archiving all of the previous HTML/CSS and starting again. Skeleton looks neat, I'll keep that one on my radar.
