add plotting

[CrepeGoat]

the results from this program are poorly legible in their current form. it would be ideal to generate a visual plot describing the results.

Thoughts:

• stacked bar graph: for every number of orbs spent (on which there are results; e.g., there's no way to spend 0-4 orbs), stack bars denoting the percentage breakdown of with what percentage outcomes occur, where every bar represents a specific outcome (e.g., for sniping one copy of a single red focus unit, each orb count will use two bars: the bottom representing getting 0 copies, and the top for getting 1 copy)
  • have each bar instead represent the number of targets pulled (e.g., pulling one green is lumped in with getting one blue)
    • this establishes a visual hierarchy: the bottom bars are "bad", the top bars are "good"; can color-code the bars to re-enforce this visual understanding
    • this reduces the amount of data to display, esp. for users trying to visualize large target counts
