Visualize glucose levels using d3.js

Demo http://bl.ocks.org/4241973

src https://gist.github.com/4241973

Dear world,

Once upon a time I sought to have real-time glucose monitoring. The best algorithms available could help me predict what my therapy was doing to me, and how I could better control the dangerous situations we encounter from day to day. But there are actually very few visualizations of this common bio-metric. See diabetes-understanding-by-simulation for more on what we hope to do with this data.

This is a quick and dirty copy of a population prediction bar graph visualization (also a demo of d3). That visualization was quickly modified to display glucose levels over time.

Some test data is used to initialize a graph, but the main graph is drawn after CSV data has been retrieved from the server.

This is a "hello world" experiment with D3 to get the basics going. It is what it is.

Eventually, it would be nice to get tiles of time segments that draw themselves so that they could be overlaid onto a slippy map. Immediate next steps however, are much more basic:

  • fix time formatting

  • get some kind of per unit of time abstractiong going

    • eg, week, or day,
    • get each unit to draw themselves
      • presumably some kind of tiling thing?
    • add pan/zoom
