NodeXL allows the user to multi-select, drag and drop nodes on the canvas and to manually edit their visual properties (size, color, and opacity). In addition, NodeXL enables users to map the visual properties of nodes and edges to metrics it calculates, and in general to any column in the edges and vertices worksheet.
Radar charts can distort data to some extent, especially when areas are filled in, because the area contained becomes proportional to the square of the linear measures. For example, in a chart with 5 variables that range from 1 to 100, the area contained by the polygon bounded by 5 points when all measures are 90, is more than 10% larger than ...
The Libre Map Project was started by Jared Benedict and around 100 additional individuals contributing money to purchase (or "liberate") a full set of 1:24K scale USGS topographic maps in Digital raster graphic form. [1] The map files were then hosted by archive.org to ensure the map data will continue to be freely available to everyone ...
Hands-On Data Visualization details design methods for interactive charts and customized maps, starting with drag-and-drop tools including Google Sheets, Datawrapper, and Tableau Public. It progresses to detail methods for editing source code templates built with Chart.js, Highcharts, and Leaflet on GitHub.

The project included visualization of the Internet data, and the Internet maps were widely disseminated. The technology is now used by Lumeta, a spinoff of Bell Labs, to map corporate and government networks. Although Cheswick left Lumeta in September 2006, Lumeta continues to map both the IPv4 and IPv6 Internet.
This is designed for transit routes, but is easily applicable for creating maps of roads, rivers, and other linear objects. For maps of shapes (neighborhoods, parks, historic districts, campuses, and most other present-day sites), see Wikipedia:Creating shape maps from OpenStreetMap data.
