Take this chart (used by Justin Wolfers in the WSJ). Which software package should you use to color parts of this chart (e.g., pre-Iowa vs. post-Iowa), and insert impacting news markers (e.g., the Michigan race)? Nigel Eccles probably knows but won’t tell. 
In other words, how could you make Justin Wolfers’ prediction market analysis visually coupled with the prediction market chart he comments on?
