Spatial analysis by the Voronoi diagram. a. Voronoi diagram. An example of the Voronoi division of an agar plate according to the spatial distribution of the colonies is shown. The tiny open circles in the right image indicate the locations of the colonies, and the irregularly divided regions represent the calculated Voronoi areas corresponding to individual colonies. b. Scatter plot of the Voronoi area and colony size. As an example, the colony sizes are plotted against the respective Voronoi areas in a single agar plate. The correlation coefficient between the Voronoi area and the colony size (cor) and its statistical significance (p) are indicated. c. Boxplot of the correlation coefficients between the Voronoi area and colony size. The tiny circles and the crosses represent the correlation coefficients of individual agar plates and the average of the correlation coefficients, respectively. Reg., Nutr. and Gen. indicate colony growth under regular conditions and in response to nutritional and genomic changes, respectively. The regular conditions and nutritional and genomic changes represent the wild-type strain growing on an LB agar plate, the wild-type strain growing on an M63 agar plate and the genome-reduced strain growing on an LB agar plate, respectively. The data used for the boxplot could be found in Table S1
