This dashboard visualizes socioeconomic trends across Nordic countries using animated line charts and a mortality-rate slider. It compares Denmark, Norway, and Sweden with interactive legends that highlight or fade each line. The mortality chart uses D3 v7’s data binding and SVG transitions to animate dots and trails over time. Tooltips display exact values, while CSS-styled grids and axes enhance readability. The background image and custom HTML structure frame the charts, with a slider controlling the displayed year.
