A line chart displays monthly risk values over time, with point markers colored green, amber, or red to indicate values below 50, between 50 and 75, or above 75, respectively. Dashed reference lines mark the 50 and 75 thresholds. The visualization, built with React and D3 v6, uses SVG for rendering and loads time-series data from a CSV file. D3's `scaleTime`, `scaleLinear`, and `line` functions generate the axes and path.
