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.

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.

TP4-grippe-france

This choropleth map visualizes the weekly incidence of influenza across French regions for 2014, using the GeoSJON file `regions.geojson` to render the regional boundaries. The map shows the cumulative number of reported cases for November 2014, with regions colored on a five-step sequential scale from light to dark red based on the total for that month. The visualization is built with D3 v3, using `d3.geo.path()` with a conic conformal projection and `d3.geo.json()` to load the geographic data. The CSV `GrippeFrance2014.csv` provides the weekly case numbers, which are summed for November and joined to the regional geometries. Hovering over a region displays a tooltip with its name and the summed value, and the color scale is computed from the minimum and maximum of these November totals.

TP4.2-grippe-france_FORK

A choropleth map of French regions displays influenza case counts per week from 2003 to 2015, with a slider to step through time and hover tooltips revealing regional names and values. The visualization loads CSV data and a GeoJSON outline, using `d3.geo.conicConformal` for projection, `d3.geo.path` for rendering, and a `d3.scale.quantile` color scale to encode intensity. Regions without data appear gray.

TP4

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.

TP4_France

A choropleth map of France colors each region by the total reported influenza cases for 2014, using a quantized green color scale. The visualization reads regional totals from a CSV file and joins them to geographic features from a local GeoJSON file via `d3.csv` and `d3.json`. D3 v4’s `d3.geoConicConformal` projection and `d3.geoPath` render the map, while `d3.scaleQuantize` maps data values to fill colors, with missing regions shown in gray.

TP4 : Grippe en France

This visualization shows the spread of influenza across French regions during the 2014 season, using a choropleth map where each region is colored according to the cumulative number of reported cases over five weeks in November. A tooltip displays the region name and its aggregated value on hover. The map is rendered using d3.geo.path with a conic conformal projection applied to GeoJSON data, while region values are calculated from a CSV file and mapped to a color scale using d3.scale.quantize.

tp4

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.

TP4

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.
