Visualize a set of plant data as a customized heatmap using R

Job ID: 36752435

Budget: $30 – $250 AUD

I have three variables (V1, V2, V3) and one treatment column.
V1 = Length
V2 = Brk Point 1
V3 = Brk point 2
These break points are happening within the V1. I would like to show the entire length and show the breakpoints along with its SD as a heatmap inside that length.
