TP2_RENDU
A simple line chart visualizes a small time series dataset, with each data point rendered as a grey circle. Hovering over a circle highlights it in red, displays the corresponding value as text, and draws a dashed vertical guide line. The chart is built with D3 v4, using `d3.scaleTime`, `d3.scaleLinear`, and `d3.line`, with data loaded from a JSON file via `d3.json`. SVG elements and mouse event handlers drive the interactive annotations.
