A pseudo line chart approximates a trend line using a single SVG path element. Rendered as a vector graphic, the chart displays a thick black curved line across a white canvas. The line’s shape is defined by cubic Bézier commands (`c` and `C`) within the path’s `d` attribute, with coordinates hard-coded in the SVG. The visualization relies on native SVG path rendering and CSS styling, including a rounded line cap and a stroke width of 10.
