[Drugmonizome Consensus Terms Appyter] Improve display & save options for output plots

[KMJ1618]

The output plots of this Appyter have tiny, blurry text that is either barely legible or illegible, depending on parameters of the display. Refer to the attached screenshot for an example. Even when I magnify my Chrome browser's page to its maximal limit, the text of some figures is still too small to read (refer to attached screenshot). It would be convenient to be able to inspect these plots within the Appyter, without having to download and save each figure in order to review it.

Additionally, for Figures 2 & 4 (stacked bar plots), clicking the "Download figure" option does not appear to produce any action. This is not true for the heatmaps (Figures 1 & 3), which successfully download.
