This scatter plot compares tourist visitor numbers between 2019 and 2021 for various places. Each dot represents a location, with its horizontal position showing 2021 visitors and vertical position showing 2019 visitors, using D3.js’s `d3.scaleLinear` for axes. The data is loaded from a CSV via `d3.csv` with `d3.autoType` for parsing. The visualization renders SVG circles styled with CSS, with axis labels added using `d3.axisBottom` and `d3.axisLeft`. The chart’s title appears above the plot, and the grid is removed for a cleaner look.
