The UMD wrapper is great for providing AMD support, but topojson and d3 are expected as globals. Unfortunately, both of those libraries also use a UMD wrapper, so if AMD support (i.e. RequireJS) is available, they will not be available as globals. So there's basically no way to use the library with RequireJS.
I think the "right" way to fix this is to define a factory that takes the globals as arguments - see https://www.npmjs.com/package/umd-wrap for one approach.
