french flag
This example displays the French flag as three vertical rectangles: a blue band, a white center, and a red band, each filling the SVG canvas. The visualization is built with D3.js version 3.5.5, using `d3.select` to append the SVG and `svg.append("rect")` to draw each stripe with explicit `x`, `y`, `width`, and `height` attributes. Colors are set via the `style` method with hex values, and the full viewport is covered by an SVG whose dimensions scale to the window. It is a static, non-interactive rendering.
