Authoring Coordinate Transforms

GoFish ships several coordinate systems — linear, polar, bipolar, arcLengthPolar, wavy, clock — and they are pluggable. This essay will be a contributor guide to the CoordinateTransform interface and how to add a new one.

Planned contents

• The CoordinateTransform type: transform, domain, and type.
• How a transform is consumed during render, and by coord's scenegraph flattening.
• Walkthrough: implementing a new transform end to end.
• Gotchas — domains, grid lines, and adaptive resampling.
