What is that ?

Our project aims to build a subgraph of the web, consisting of the French websites mentioning open-data. This graph enables viewers to see popular websites and connections between them, to see which kind of entities communicate with the others (Companies, Non profits/Blogs, Government agencies). It is a good way to discover the actors of the French open-data, and how they relate to one another.

The nodes are manually grouped by categories: type (Companies, Non profits/Blog, Government agencies) and roles (Open-Data Speaker, Open-Data Dealer), which led to two different graphs, accessibles via the menu.

Graph analysis is available on our website, in the blog post describing this project (post in french).


We used Common Crawl as a resource to gather the websites we needed to build our graph.

We used Gephi to visualize and spatialize our graph.

We used sigma.js to embed our graph on this website.
