Different edge lengths on Graph

Hello, I am drawing evolutionary trees where edges are supposed to represent evolutionary distance. This means TreePlot or GraphPlot, but I am not sure how best to draw the different edge lengths. If for example I have, TreePlot[{1 -> 2, 2 -> 3}] but I want the length of the edge (1->2) to be smaller in size than from (2->3). I was thinking about getting the raw output from TreePlot and making some changes. Any suggestions? Thank you, Ramiro
