This visualization shows the annual incidence of influenza across French regions in 2014, using a choropleth map with an orthographic projection. Regional totals are aggregated from weekly case counts and displayed as colored polygons, with a tooltip showing each region’s name and total. The map is rendered using `d3.geoOrthographic()` and `d3.geoPath`, with regions colored via a linear scale from white to green and hover interactions managed through D3 event handlers. Data is parsed from a CSV file and joined to GeoJSON features.

A choropleth map displays the annual sum of influenza cases across French regions in 2014, colored on a white-to-green scale. Hovering over a region reveals its name and total count via a tooltip. Built with d3.v4, it uses `d3.geoOrthographic` projection, `d3.geoPath` for rendering GeoJSON, and `d3.scaleLinear` for color mapping. Data comes from the GrippeFrance2014.csv file, merged with regional geometries from regions.json.

An interactive choropleth map visualizes weekly influenza case counts across French regions in 2014 using D3 v4. A slider controls the displayed week, updating region fill colors from a linear color scale representing case numbers, with tooltips showing exact values on hover. The map uses an orthographic projection via `d3.geoPath` and loads geographic boundaries from `regions.json` while parsing CSV data from `GrippeFrance2014.csv`. Missing data renders regions in grey.

This choropleth of French regions displays the weekly incidence of influenza for November 2014, with color intensity mapped to the sum of reported cases for those weeks. Built with D3 v4, the visualization uses `d3.geoConicConformal` for projection, `d3.geoPath` to render the map from a GeoJSON file, and `d3.scaleQuantize` to assign chromatic classes. Values are loaded from a CSV containing weekly regional data, and a tooltip appears on mouse-over to reveal the specific regional total.

A choropleth map of French regions shows the weekly incidence of influenza-like illnesses during 2014, with a slider to step through the year and a tooltip on hover. The map uses d3.geoConicConformal and d3.geoPath to render region boundaries, while a d3.scaleQuantize maps case counts to a five-color scale. Data is loaded from a CSV and joined to GeoJSON features, with the legend displayed as colored rectangles.

The visualization is a choropleth map of France showing the cumulative number of influenza cases per region for November 2014. A geographic projection renders each French region as a colored path, with a five-color quantized scale mapping the summed weekly values. The map, built with D3 v3, uses `d3.geo.conicConformal` for projection and `d3.geo.path` for drawing, while a mouseover tooltip displays the region name and its computed total. Data comes from the CSV file `GrippeFrance2014.csv`, with values merged into the GeoJSON features.

This choropleth map displays the cumulative number of influenza cases across French regions for the weeks of November 2014. Each region is colored on a five-step green scale, with darker shades indicating higher totals, and hover tooltips reveal exact values. The visualization merges CSV data with geographic boundaries using D3’s `d3.geo.path` with a conic conformal projection, while `d3.scale.quantize` maps data values to the color range. The code also demonstrates layering multiple GeoJSON loads and integrating mouse events for interactive detail.

A choropleth map of France displays the cumulative seasonal count of influenza cases for each region in 2014, colored from white to green on a linear scale. The visualization loads regional data from a CSV file and geographic boundaries from a GeoJSON file, then merges them. It uses `d3.geoConicConformal` and `d3.geoPath` to draw the regions, while a D3 linear scale with an HCL interpolation maps the summed yearly values to the color range. Hovering over a region reveals its name via a tooltip.

A choropleth map of France displays the cumulative influenza case counts for the last five weeks of 2014 across the country's regions. The visualization renders the geographic boundaries from a GeoJSON file using the D3.js `d3.geo.path()` and a conic conformal projection. Regional values are joined from the GrippeFrance2014.csv data, mapped through a five-color quantized scale, and displayed as tooltips on mouseover. The code uses D3 v3 and the TopoJSON library.
