Today's graph is a map-based infographic showing the distance from Kansas City to all other Major League cities. The distance is shown by the colour of the arrows, where the colour is based on RGB values. The formulas for these values are given by:
where dist is the distance from the given city to Kansas City. The constants are shown below:
Given all the above, presented next is a set of instructions on how to use the maphographic. First, eyeball the RGB values of the desired arrow. Next, re-arrange the three colour formulas to isolate the variable dist. Input the constants given above, and solve for dist. Voila: now you can easily find the distance from Kansas City to any other city with a Major League Baseball team in just a few simple steps. Feel free to pass this handy tool along!
Note: Toronto's arrow colour is based on kilometres, and is therefore darker than one would expect for an American city with a similar distance.
