The checkerplot is a new type of graphics that combines geographical information and plots. Hereby, traditional plots like barplots or polygon lines are visualized in geographical order on a grid. The checkerplots can be seen as a mixture between thematic maps and the grid-representation in trellis plots.

More precisely, a checkerplot a stylized map in rectangular grid-like form (like a checker board), in which geographical position and neighborhood are approximately (as best as possible) maintained. Therefore, for all geographical entities an equally sized plotting region exists on a grid.

The checkerplot combines all advantages of traditional statistical graphs and representation in thematic maps:

- All areas have equal space for presenting (even complex) statistical information.

- The geographical position of the areas are approximately maintained.

- The common baseline of t
