D3 based data visualization of a context map
A context map is a visualization that explain why certain markers (entities) on a map gravtitate toward black dots which represent context. A context map is made by feeding multiple matrices of data like income, popularity, and cultural importance through a technique called non-negative matrix factoriation.
Through that technique, you get output whicn you plot onto a map which visualizes elements gravitating toward certains states. The black context dots represent why elements gravitate toward it. The black contexts dot visually represent a bunch of matrices of data.
The code for this visualization can be found here .
