Title
This chart compares international tourist arrivals for the top 10 countries between 2019 and 2020 using a Cleveland dot plot. Green dots represent 2019 values, while purple dots show 2020 figures, connected by grey lines to highlight the dramatic decline due to the pandemic. The visualization is built with React, D3 v6, and SVG, using `d3.scaleLinear` and `d3.scaleBand` for axes. Hovering over purple dots triggers a tooltip via mouse events, and a legend is generated using the `d3-legend` library. Data comes from the included CSV file.
