A world-view cartogram for World's Aids Day. The size of a region indicates the number of people infected with HIV - each square being 10,000 people infected. The colour of a region indicates the rate of infection, in relation to the global average.

The three maps show Local Authorities with (1) high levels of BNP membership, (2) large non-white populations, and (3) both high levels of BNP membership and large non-white populations. The use of the blue, red and overlap purple colours make this a geographic "Venn diagram", allowing viewers to quickly identify areas with high levels on two separate datasets.

The two maps both show levels of recorded crime across Leicestershire at Lower Super Output Area LSOA level (with darker red representing higher levels of crime). The map on the left shows the actual geography of the LSOA areas across the County. LSOA areas each contain roughly 1,500 residents - larger areas on this map therefore represent rural areas with lower-density population. The cartogram, or distorted, map on the right shows the same data at LSOA level, but represents each of the LSOAs as a fixed size hexagon. This avoids the problem of over-emphasising the more rural LSOAs, seen on the left. However, it becomes more difficult for users to understand which areas are which - so a numbered key is used to identify particular areas.

This map presents information about the murder rate in the United States during 1976. It shows the rates in six intervals, relying on several smaller maps to do that.

This chart is designed to aid the interpretation of the results of a cluster analysis, a statistical technique used to discover the underlying structure of a set of observations. The data set contains dummy variables.
