There needs to be a modal dialogue (that can be minimized) that provides some explanation of each major interaction with suggestions on related interactions. For instance, when you run a route, it should note that you could change the month or priority to see a different route, or when you run a cartogram it explains the next steps in the process to get to clusters and borders.

Borders only work when after resetting geographic locations with the "Cartogram Off" button.

Rather than just distorting sites, the cartogram should also distort routes, either using distorted geo for the routes (requiring georectification/custom projection) or at least with straight lines connecting them.

Transfer Cost is currently applied universally to all transfer types. User should be able to set specific costs for river, coastal, overseas, ferry.

Custom projection could be used to rubber sheet the Mapbox terrain to the distorted geography of the cartogram, but this would require not only serious computation but also some kind of visual method to represent the distortion that occurs when a distant coastline is "closer" than an inland region. For instance, inland Spain is "farther" from Rome than the Atlantic Coast of Spain if measured by speed or expense.

Current sites csv is not alphabetized and should be sorted in js.

Currently it's mostly donkeys.
