Summary

The previously (in the thesis) analyzed design concept of Galton serves as an inspiration for efficient use of space in visual communication. Much data is represented graphically in a small place. Additionally, the application possibilities are versatile—on the one hand, the system can be used to cover the entire area of a map, on the other hand, the individual sections can stand on their own, representing isolated locations, like Galton already did. This is a convenient basis for revising his ideas in light of Edward Tufte’s “graphical excellence”. The primary motivation to redesign this approach is that it takes the data from forecasts and converts tables of numerical values into graphics using little space yet remaining visually comprehensible. To express the aim of the prototype, some points from Tufte’s list shall be repeated: it is aimed to show the data—without distorting or distracting it, present many numbers in a small space and make large data sets coherent, encourage the reader to compare different pieces of data, giving different levels of detail from fine structure to broad overview.
