This chart shows how many people visited a location each year from 2010 to 2019, combining a smooth blue line for the trend with a filled yellow area beneath it. The visualization uses d3.scaleTime and d3.scaleLinear to map the date and visitor count, with d3.line and d3.area generators using a curveBasis interpolation. Data is loaded from a CSV file, and the axes include formatted tick labels with grid lines, rendered as SVG elements.
