+# iTunes Graphs
+
+![](screenshot.png)
+
+iTunes Graphs is a Cocoa-based macOS app which visualises your iTunes library in a series of pie charts.
+Currently, it supports the following graphs:
+
+ - Artists
+ - Genres
+ - Decades
+
+There's no build on GitHub at the moment, so you'll have to build it yourself from Xcode. Use Xcode 8.
