Selling Honey at Farmers Markets, Shops and Country Shows: Sales-Channel Economics (2D)

This 2D companion runs the identical greedy sales-channel allocation as the 3D market-square scene — the same price, supply, stall-fee, commission and show-frequency inputs feeding the same per-channel capacity and fixed-cost rules — but reads it as three linked charts instead of an orbitable scene: a capacity bar for each channel showing exactly how many jars land there this month, a profit bar chart that turns red the moment a channel's fixed cost outweighs its sales, and an effective-margin-vs-commission curve, unique to this view, that amortizes each channel's flat fee across its own full capacity so you can see precisely how far commission or stall fees have to rise before a channel that wins on paper actually stops paying for itself.
