A flow map visualizes the geographic spread of a single day's Twitter links, sourced from a Gist and plotted as points on a basemap. It uses the D3.js library, with `d3.geoPath` to render country boundaries and `d3.geoGraticule` for the graticule, while a force-directed layout (`d3.forceSimulation`) positions nodes representing each URL. The map encodes each tweet's source location and destination via curved lines, with color and opacity indicating interaction intensity. The geographic projection and point placement are computed using the `d3.geo` module.
