The visualization shows the evolution of TER (regional express train) traffic quality across French regions from 2013 to 2017, mapping monthly percentage values onto a choropleth of France. The view is updated via a slider that changes the displayed month. The code uses D3 v4 with `d3.geoConicConformal` for the map projection, `d3.geoPath` to render region outlines, and a quantized color scale. Region values are loaded from the CSV file containing a row per region and columns for each month, then joined to the GeoJSON regions by matching region names.

Vizu_Part1_Map

This interactive map visualizes regional TER train flow quality across France from 2013 to 2017. Users adjust two sliders to select a specific month and year, and the map updates its choropleth coloring accordingly, with a legend and hover tooltips showing precise values. The visualization uses D3 v4's `d3.geoConicConformal` projection and `d3.geoPath` to render the regions, while a color scale (`d3.scaleQuantize`) encodes the data from the provided CSV file.

Viz_Part2_Compare

This example uses an interactive choropleth map of French regions to compare monthly traffic data from the TER regional rail network across two selectable years (2013–2017). The visualization features two side-by-side maps, each with separate sliders for year and month, allowing direct visual comparison through the shared color scale. The maps are drawn with `d3.geoPath` and a `d3.geoConicConformal` projection, while color values are mapped using `d3.scaleQuantize`. Data is loaded from a CSV file containing monthly statistics per region. Hovering over a region reveals a tooltip with its name and value.

Dorling Cartogram

A Dorling cartogram of French regional rail traffic displays monthly ridership data from 2013 to 2017. Each region is represented by a circle positioned near its geographic origin, with circle size and fill color encoding passenger counts. Interactive sliders let viewers select a year and month. The visualization uses `d3.forceSimulation` for non-overlapping circle placement and a `d3.geoConicConformal` projection for initial locality. It merges CSV travel statistics for regions with GeoJSON outlines via `d3.csv` and `d3.json`.

Gist 496f20b47774ec679ab5dd48beff9d7e

This example maps French regional data from a CSV file onto a geographic outline of France. It uses a conic conformal projection and a quantized color scale to shade each region according to a numeric value. The visualization loads GeoJSON topology for the region boundaries and joins it with the CSV data, filling regions with a five-step green color ramp, while regions without data appear gray. The code relies on D3 v4’s `d3.geoConformal`, `d3.geoPath`, `d3.scaleQuantize`, and CSV/JSON loading functions.

Projet_DataViz_Histogramme

This example shows the monthly regularity of TGV trains on French routes, displayed as a bar chart of the number of delayed trains per month. It begins by filtering a CSV of train records (tgv_annees.csv) to a selected origin–destination pair and year, then renders the resulting monthly counts as labeled bars using SVG. The visualization is built with D3 v4, using `d3.csv` for loading, `d3.scaleLinear` and `d3.scaleBand` for axes, and `d3.axisBottom` for the month labels. The code follows a reusable chart module pattern, with the main chart logic in `histogram-chart.js`.

[DataViz] TP4

A choropleth map of French regions colors each area by the total number of flu cases reported in 2014, using a quantized color scale. The visualization also displays the aggregate count of cases for November in a text box. A slider input allows navigation through the weeks, and hovering over a region reveals a tooltip with its name and annual total. The map uses `d3.geoConicConformal` for projection and `d3.geoPath` to render the shapes, with data from the CSV file merged into the GeoJSON features.

Dorling Cartogram

This interactive Dotting-style cartogram displays monthly regional train delays across French administrative regions from 2013 to 2017. A Dorling-style map replaces geographic polygons with circles sized by delay magnitude, with slider inputs to select month, year, and toggle between map and node views. The visualization uses d3.csv and d3.json to load data, d3.geoPath with a geoConicConformal projection, d3.scaleSqrt for circle radii, and d3.scaleQuantize for color encoding. Hovering reveals tooltips with precise values.

Projet_DataViz_Matrice_Histogramme3

This block combines a monthly histogram with an adjacency matrix to visualize the punctuality of TGV and Intercité train routes in France. A slider selects the year, and radio buttons switch between train types. The code uses `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisTop` to render the SVG matrix and histograms. Data for stations and routes with punctuality weights is loaded from CSV files, and interacting with the controls re-renders the visualization.
