A line chart visualizes the monthly total count of homeless individuals from a CSV dataset, plotted over time. The Svelte application uses D3 scales (`scaleTime`, `scaleLinear`) to map data to pixel coordinates, with a white line plot connecting the data points. Circles at each point enlarge on hover via GSAP animations. The visualization includes custom SVG axes for the date and value ranges, with the chart's dark background from the main stylesheet.
