TopoJSON Time Zones

download the Natural Earth 1:10m Time Zone Data (GeoJSON available from CartoDB)
run topojson --post-quantization 1e3 --simplify 1e-5 --out timezones.json -- ne_10m_time_zones.geojson

The result is this 181 KB timezones.json (36 KB with gzip)

Except for the code segments that render the magnifying glass (as circle or path), this is essentially a copy of Mike Bostock's Fisheye Distortion example.

The motivation for this was largely aesthetical but also a bit functional. When using the Fisheye as an aid to viewing large datasets, I often find myself experimenting with the degree and radius of the distortion. In such cases, I find it helpful to see the exact reach of the distortion and then decide the best configuration for a particular dataset.
