Color the marks by if the QB's school is in the Big Five, Group of Five, or Independent - no restrictions
Explanation: We are encoding categorical attributes and only four bins needed including the background, thus, colors with different hue are appropriate choice
Color the marks by if the QB's school is in the Big Five, Group of Five, or Independent - color-blind safe
Explanation: For this graph, we do not include red color, for color-blindness safety. differentiation in red-green channel is reduced or totally absent for color-blinded people
Color the marks by if the QB's school is in the Big Five, Group of Five, or Independent - photocopy safe
Explanation: In this graph, because we have categorical attribute to encode with color, then we have to have different hue colors. but again in order for this to be photocopy-safe, we need to have different luminance for each color choice
Plot only QBs from schools in the Big Five conferences. Color the marks by conference - no restrictions
Explanation: We have six bins including the background. Thus we are using hue color map with different color for each conference. Here we cannot have both photocopy-safe and color-blind friendly, because number of bins are too high to have an appropriate choice
Plot only the top 5 QBs by rank and color the marks by rank. choose a multi-hue colormap
Explanation: We are using ranking which is a sequential attribute. Thus, we start with darker color for the higher rank to lighter color for lower rank
Plot only the top 5 QBs by rank and color the marks by rank. choose a single-hue colormap
Explanation: Explanation: We are using ranking which is a sequential attribute in a single hue colormap. Thus, We assign higher saturated color to the higher rank and lower saturated color to lower rank.
