This Sankey diagram shows the ownership structure of major French newspapers, tracing each title through holding companies and parent groups down to the ultimate individual or institutional owners. Link thickness encodes the percentage of ownership, while node drag-and-drop allows for interactive exploration of the hierarchy. The visualization is built with D3 v3, using the `d3.sankey` layout on CSV data, with SVG paths for links and rectangles for nodes. Node colors are assigned via a categorical scale, and tooltips display exact ownership percentages.

AI-generated description

Les principaux propriétaires de titres de presse française. L'épaisseur des connecteurs indique le pourcentage de propriété, par ex. Le Monde SA possède 100% du journal Le Monde, mais Le Monde SA est propriété de l'entreprise Le Monde libre à 64%.

Ce diagramme accompagne des articles écrits dans le cadre des explorations de données Désidédata ; voir par ex. "Quelles évolutions des aides à la presse française ?".

Ce diagramme de Sankey a initialement été utilisé à titre d'exemple dans le livre D3 Tips and Tricks. Une version plus simple est également disponible. Le fichier de données est un .CSV ; ce diagramme est un fork de <a href='http://bl.ocks.org/d3noob/c9b90689c1438f57d649'>d3noob</a>.

Qui possède quoi

This interactive network diagram maps the ownership structure of French media outlets, revealing which individuals and companies ultimately control specific newspapers, magazines, and radio stations. It visualizes hierarchical relationships through a force-directed graph, with edges representing ownership percentages and nodes categorized as ultimate owners, intermediate groups, or media properties. The visualization uses D3.js v3’s force layout to position nodes, with SVG circles and rectangles for entities. Data comes from a CSV file containing ownership chains, parsed and converted into JSON for hierarchical linking, and the interface is built with Vue.js.

A qui appartiennent les médias?

This visualization maps the ownership hierarchy of French media outlets, showing how individuals and parent companies ultimately control various newspapers, magazines, radio stations, and websites. It displays a network of nodes representing owners, corporate groups, and media titles, with connections illustrating the percentage of ownership at each level. The data, sourced from the CSV file `basemedia.csv`, is presented using the D3.js force-directed layout (d3.forceSimulation), rendered as SVG elements. The interactive view allows zooming and dragging to explore the relationships.

This visualization maps the ownership structure of French media outlets, showing which individuals or companies ultimately control various newspapers, magazines, and radio stations. It uses a node-link diagram where possessors, holding groups, and media outlets form a hierarchical network. The layout is generated with D3.js v3, using a force-directed algorithm to position nodes, while SVG elements render the graph. Data is loaded from a semicolon-delimited CSV file, and the styling includes highlighted nodes for active elements.

Jam Cellar 2014-05-06

This visualization maps French media ownership as a concept map, showing which proprietors (Claude Perdriel, Prisa, Pierre Berge, Xavier Niel) control various publications like *Le Monde* and *L’Obs*. Each inner node represents a media outlet, linked to outer nodes showing ownership layers with percentages. Built with D3 v3 and Vue, it uses SVG for rendering and `d3.scale.linear` for layout, with data loaded from a JSON file via `d3.json`. Links and nodes are sorted and positioned programmatically to highlight ownership hierarchies.

This example maps media ownership in France using a two-tier node-link diagram that shows which owners control which publications. The view separates inner nodes for media outlets from outer nodes for corporate owners, with links indicating ownership stakes and percentages. It uses D3 v3 scales and custom layout logic to position nodes, and renders the structure as SVG with interactive highlighting. The data comes from a JSON file listing ownership relationships across French media properties.

Les couleurs du Décodex

The visualization maps the websites reviewed in Le Monde's "Décodex" fact-checking tool, positioning them with a t-SNE algorithm to group sources sharing similar keywords in their descriptions. Each site appears as a colored circle—green for reliable, blue for satirical, orange for imprecise, red for false information, and gray for non-sources—with a tooltip revealing its name and the Décodeurs' comment. The layout is computed in a background worker using the tsne.js library, while d3.forceSimulation and d3.forceCollide arrange the labeled nodes in the final SVG. Data is fetched live from Le Monde's webservice, and clicking a node opens the corresponding source page.

TP 6 DataViz 2

A force-directed network graph maps voting patterns among French National Assembly members, filtering links to those with at least 15 shared votes. Nodes are colored by political group and labeled with member names and affiliations. The visualization uses D3 v4’s `d3.forceSimulation`, `d3.forceLink`, and `d3.forceManyBody` with SVG rendering. Data comes from the `scrutins.json` parliamentary roll-call votes and `acteurs_simple2.json` member metadata, loaded via the `queue` library.
