Thanks! I think frameworks are overkill for such small projects, setting up a full project e.g. using React, Babel, Webpack, D3 and SASS would have taken me longer than I needed to finish this whole project, I think :D Most modern browsers have really good support for JS and CSS so you don't need any additional libraries. It's the date on the first graph, I'll add a more obvious format that will be readable for English/US speakers as well (in Germany/Europe the date format is often dd.mm).
