Panther is a full-stack React/Redux/Node web app that uses the Spotify API to make suggestions based on an initial user-specified artist. It uses a graph consisting of vertices and edges to represent the data. At the center, the user's currently-selected artist, along with the artist's avatar and some audio samples of the artist's top tracks. To the left is a vertex representing the previous artist, and to the right are 3 suggestions. By clicking on the vertices, users can move forwards and backwards through their suggestion tree, (hopefully) discovering a bunch of awesome new music.
