These two visualizations depict data from the FCC International Traffic Data Reports, by region for 2011, and a time series showing traffic by year from 2002 to 2011. The report makes available data on international telephone, private line and miscellaneous services between the United States and other countries.
- View Traffic by Year
- View Traffic by Region
This project is one of a number of novel visualization tools being used to communcate policy issues in new formats. These pages allow the public to investigate the call traffic data in a unique way, and to see changes in patterns by year and by region.
Information on the Annual International Traffic Report can be found on The FCC’s International Bureau page on International Telecommunications Traffic Reports
Both visualizations are driven by D3.js, the javascript library by Mike Bostock. D3 is a powerful tool for manipulating data in the browser, and can bring your “data to life”. For more information on D3, visit the d3js.org page.
FCC makes the Annual International Traffic data available by year. These data are converted to json format and then assembled into a single json file. Data are available in the /data folder.
Libraries used
- D3.v3 for charting and mapping
- Queue.v1.js for asynchronously loading data
- Topojson.v0.js to create and consume world boundary spatial data in topojson format
We also use bootstrap.css for styling, and Jekyll for Github Pages generation.
The Traffic By Region (bubble chart) was inspired by this NY Times Chart and this great tutorial by Jim Vallandingham.
