This month Steve Mallet presents epidemiology data on measles, polio, and rubella from the 20th century.  The challenge is to display the incidence change over time, especially after the availability of the vaccine. Visualisations are available on the Wonderful Wednesday blog.

To visualise the big amount of data in one plot heatmaps were used. Having the time on the horizontal axis is intuitive and helps to quickly understanding the data. On the vertical axis the way of sorting or arranging the data can support understanding of relationships. One question is how to display missing data. Another question is when to use diverging and when to use sequential colour scales. Have a look. The new challenge is on benefit-risk assessment. See the Wonderful Wednesday homepage for more detail.
