+### uPlot
+
+For displaying graphs, the [uPlot library][uplot] is used. Because this is the
+only dependency on the JS side, I decided not to use a package manager and
+instead just add the library files directly.
+
+To update the uPlot files, run `./meta/update_uplot`. This will download the
+required files from uPlot's master. The `uPlot.d.ts` file's export statement is
+patched to resemble the one in `uPlot.js`. This way I don't have to enable
+`esModuleInterop` in my `tsconfig.json`.
