First let me back up and say, if you have read the research available on the items below and come to the current design after very careful thought, then I am just a jerk giving immediate negative feedback on your hard work and I hope you will forgive me. But if, as I suspect, you have given a lot of thought to the medical, statistical, and visual side of this, but are not well-read in the research on information display, I hope my suggestions will be helpful. - I would recommend being very careful with the wording. One can have too much "food" but "nutrition" has positive connotations and no lay person would speak of "too much nutrition" or "too much environment". - Please read the experimental material on information display. People study these things and polar display is very poor for picking outliers and recognizing patterns relative to almost any other option, including just printing numbers next to labels with no graph. - For building "interactive" data displays, please read Bret Victor's "Magic Ink", specifically the section on the evil of requiring interaction to display information. [1] One of the problems of the circular layout is that 18 is about as many items as can fit, thus you need interactions to see more data. With most other displays of this data, you could easily fit far more information into one, interaction-free display, which could even be printed out for use in a wider variety of contexts. - You could also use the clearer display to show actual numerical labels or trends over time. (Surely someone with high but declining blood pressure should appear different than someone with high and increasing blood pressure.) - Finally, I am very curious about the decision to include the same set of metrics for everyone and to display them as a single graph. Some of these metrics belong together on one scale, some belong on separate scales, some belong only on people with specific conditions, etc. - Are you planning to do a controlled test of this against other high-level patient summaries? Obviously my guess is that this graph and its interactions would fare worse than a one-sentence textual description provided by a past doctor. "Patient is a well-dressed and intelligent elderly man, with a successful history of controlling his diabetes through diet and exercise, but still showing signs of hypertension" seems to me much better than a graph with conditions: red that requires zooming in to see the word "diabetes" and LDL right on the edge that requires zooming in to see a declining trend over time.
