The Right Data: ESPN's line graph regarding win chance doesn't use any new or complex visualization; instead it chooses a unique data set to convey the desperation of last night's Super Bowl. ESPN uses past games' scores and field positions combined with win rates to graph the historical chances of a Patriots victory at each point in the game.
The Right Format: The below source features two ways to visualize the same data on the way the game's airtime was spent, each of which seem to present conflicting portraits of the game. The first, showing a linear chronology of bar widths representing content, suggests continuous stimulation everywhere except the halftime show. The second, a simple pie graph, suggests a long and boring majority of replays and commentary with only a tiny isolated portion of excitement.
