Evolutionary Computation for Label Layout on Unused Space of Stacked Graphs

Figure 1

Stacked graph view (left) showing 40 job occupation names starting with the prefix “A”, and TLV = 0 pixels. A number of labels are illegible due to either overlapping or small size. The solid line encloses the visualization area, and the dotted line the unused space. At the right, an increased section of the same view (top) with TLV = 12 pixels (some labels are hidden). The same section (bottom) can be seen with TLV = 0 (some labels are overlapped) and with their minimum font size increased three times.
