Work samples

All examples were realised with IBM Planning Analytics powered by TM1, Microsoft and the GMC² Report Controller.

  • Population density distribution The population density distribution in Germany is presented for the years 1950 to 2020. Small multiples were used, because they deliver ideal capabilities for presenting the ratio 'population density in deviation from the average of all cities'. The cities were ranked by area size, so the message can be clearly delivered.

  • Vacant office space The grouped bar graphs represent the first level of the vacancy of the German states grouped by East and West. The second and third levels show the deviations in absolutes and percentage. The message is supported by the highlighted absolute deviations.
