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.

Oldham Neighbourhood Wellbeing Index. A modified traffic light scheme is used in the maps with red - indicating rates ranked in the highest 10% band, amber - the high 11-25% band, light green - the low 11-25% and dark green - indicating rates ranked in the lowest 10%. In maps displaying rates across the four themes, neighbourhoods with rates ranked in the 26-74% band are white, whereas in maps of trends and sudden changes, those neighbourhoods are shaded yellow, whilst those in white show no trend or sudden change. White is also used for neighbourhoods where no persistently high or low rates are detected. It is in this way that the maps themselves act as visual exception reports.

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.
