rust_d3_geo

• The public API has been reviewed, many internals were relegated to pub(crate), pub(super) without reducing functionality.

• Recently about 10% speedup was achieved by migration to using web_sys::Path2d

• Dependencies were review, a crate that is no longer maintained was removed, for security concerns. A side effect of this is that multiple version of the same crate were streamlined to a single version, reducing the footprint of the library

The library feels in a good place.
