WEEK 12: How Different Groups Spend Their Day

[lzhang]

The critique is excellent.

This visualization is essentially a stacked time plot for multiple time series. Each time series represent the percentage of people among a specific group performing certain activity. For example, the orange band represents the percentage of people who are working.

Since the time series are stacked, the value of the time series at each time point is represented by a vertical span. This encoding is unaligned spatial position. This strategy works well for time series with large spans, like "work"". However, it performs poorly for time series with small spans, like "job search" (the 6th band from the top). The author use interactivity to resolve this problem. However, since the band is so thin, it is still difficult to locate the band. Maybe we could put some legend on the side and by clicking the legend we can select the corresponding band.
