Roll your own TopoJSON from Natural Earth data.

This repository provides a convenient mechanism for generating TopoJSON files from Natural Earth. Before you can run make, you’ll need to install Node.js, topojson and the gdal package for your system.

yum install gdal-perl gdal-doc gdal
npm install -g topojson canvas

If you want to install this software using an alternate method see the website for TopoJSON. I also recommend reading Mike's tutorial, Let’s Make a Map.
