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 visualization presents a choropleth map of France, coloring each region according to the total reported cases of influenza (grippe) during November 2014. The data is loaded from a CSV file and joined with geographic boundaries from a GeoJSON file. It uses D3.js v3 with a conic conformal projection and a quantized color scale, and includes a tooltip that displays the regional name and value on mouse movement.

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 metropolitan France displays weekly influenza case counts by region for 2014, with a slider to navigate through the year. The visualization uses d3.geoConicConformal for map projection and d3.geoPath to render regional boundaries, with fill colors assigned via d3.scaleQuantize. A hover tooltip shows the region name and case value. Data comes from the GrippeFrance2014.csv file, which is merged with the france.json GeoJSON structure.

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 regional influenza consultation data for 2014, with each region colored on a green sequential scale according to weekly or monthly case counts. The visualization uses D3 v4 with `d3.geoConicConformal`, `d3.geoPath`, and `d3.scaleQuantize` to render SVG paths from the `regionsFrance.json` GeoJSON file, while a CSV file provides the data. Hovering over a region reveals a tooltip with its value.

TP4-grippe-france

A choropleth map of France displays the total number of influenza cases in 2014 for each region on a conic conformal projection. The visualization uses a five-color quantized scale to encode the cumulative case count (`somme2014`) for each region from a CSV file. The geographic boundaries are loaded from a GeoJSON file and merged with the data, with the fill color for each path computed via `d3.scale.quantize()` and `d3.geo.path()`. Regions without matching data appear in gray.

This interactive choropleth map displays weekly influenza case counts across French regions for 2014. A slider lets users step through each week, updating region colors through a quantile scale. The visualization uses D3 v3 with `d3.geo.conicConformal` for projection, `d3.geo.path` for rendering GeoJSON regions, and a custom tooltip on mouseover. Data comes from the GrippeFrance2014.csv file containing weekly regional counts.
