Read the Rate

Start with three pinned channel rows. Each row has visitors and orders. For each row, compute orders / visitors. Email is 12 / 120 = 10%, search is 6 / 100 = 6%, and ads is 3 / 50 = 6%. The bars show the derived percentages, not the raw visitor counts.

A tiny derived-rate readout: start from visitors and orders, compute orders divided by visitors, and plot the pinned percentages.
