##using D3 and the Spotify API ###Front-End Capstone Project for Nashville Software School

##Project Goals:

Determine to what extent a given song's tempo speeds up or slows down over the course of a song.

Interpret large data sets. Spotify's API provides a detailed analysis file for each song in its' catalogue, including the length of each beat, bar, etc. in that song.

Example from a Spotify song analysis file:

"beats": [
    {
      "start": 0.19322,
      "duration": 0.42275,
      "confidence": 0.061
    },
    {
      "start": 0.61597,
      "duration": 0.42643,
      "confidence": 0.896
    },
    {
      "start": 1.0424,
      "duration": 0.41907,
      "confidence": 0.955
    },
