Major League Soccer v2

Major League Soccer season data (2006 - 2016)

Slight riff on /cjhin/11ffe8165207693d513ad67f85d43251

This version uses d3 force layouts (and d3v4) to make it easier to read the nodes/circles. The catch is that b/c the force layout pushes the nodes horizontally, it's no longer possible to show as many years.

For now, this just shows a condensed chart of the past 10 years, theoretically at least one solution would be to make the chart "horizontally" scrollable"

How To:

Hover over a point to view data for that club/season.
Click on a point to highlight all data points for that club.

Sources:

Data scraped from http://www.mlssoccer.com/standings/mls
Most colors are from http://teamcolors.arc90.com/
