Fig. 4.

The relationships between d0 and bifurcation angle with k illustrating that k is highly variable at small d0 and converges on values near 3 (Murray’s Law) at larger d0 and that k progressively diverges from 3 at larger bifurcation angles. For ease of comprehension, each point in the scatterplots represents the average value for twenty observations. Bifurcations were sorted by d0 (ag) and angle (hn) before being binned into groups of twenty. The raw data are presented in the supplemental figures. Note that because panels a–g illustrate the absolute deviation from k = 3, the mean deviation will not reach zero simply due to measurement error or any small deviation
