This multi-line chart displays three data series (A, B, C) over a two-week period in July–August 2019, plotting daily measurement values. Each series is rendered as a distinct colored path with different dash patterns, accompanied by end-of-line labels. The visualization uses D3 v5 with an SVG viewBox for responsive scaling, d3.scaleTime and d3.scaleLinear for axes, d3.line with default curve interpolation for paths, and d3.axisLeft/axisBottom for gridlines. Data comes from an inline CSV file.
