eulerAPE: Drawing Area-Proportional 3-Venn Diagrams Using Ellipses

Figure 11

Examples of diagrams generated by venneuler and eulerAPE (circles and ellipses) for data in L2.

Examples of diagrams generated with (i) circles by venneuler, (ii) circles by eulerAPE, and (iii) ellipses by eulerAPE for random 3-set data in L2. (A) Diagrams generated for data {a = 3491, b = 3409, c = 3503, ab = 120, ac = 114, bc = 132, abc = 126}. Ai is missing region abc and has stress = 5.69×10−4 and diagError = 1.16×10−2. Aii and Aiii have the required regions, one for every data set relation. Aii has stress = 8.36×10−3 and diagError = 2.63×10−2. Aiii has stress = 3.96×10−12 and diagError = 6.55×10−7. (B) Diagrams generated for data {a = 45910, b = 3261, c = 45467, ab = 58845, ac = 3028, bc = 16406, abc = 18496}. Bi is missing region ac and has stress = 3.17×10−3 and diagError = 2.07×10−2. There are two regions in Bi depicting only b. Bii and Biii have the required regions, one for every data set relation. Bii has stress = 2.13×10−2 and diagError = 4.36×10−2. Biii has stress = 3.43×10−12 and diagError = 6.85×10−7. (C) Diagrams generated for data {a = 3664, b = 46743, c = 59811, ab = 1742, ac = 2099, bc = 17210, abc = 24504}. Ci, Cii and Ciii have the required regions, one for every data set relation. Ci has stress = 4.27×10−3 and diagError = 2.30×10−2. Cii has stress = 8.31×10−3 and diagError = 2.44×10−2. Ciii has stress = 1.13×10−12 and diagError = 4.03×10−7.
