This example displays a small, empty SVG canvas with a fixed height of 75 pixels, embedded in an HTML page. The code sets up a D3.js geographic projection using `d3.geoConicConformal()` centered on France, along with a `d3.geoPath()` object, but the SVG group for departments is appended without any geographic data being drawn. The visualization shows only a blank map area, as the data source and rendering steps are not implemented in the provided files. It demonstrates the initial setup for a React-based SVG visualization using D3 v5.
