This scatter plot visualizes tourist visitor counts across U.S. states, comparing 2019 figures on the x-axis with 2021 numbers on the y-axis. Each circle represents a state, with data loaded from a CSV file via `d3.csv` and rendered as SVG elements using `d3.axisBottom`, `d3.axisLeft`, and `d3.scaleLinear`. The chart includes axis labels, a title, and a subtitle, while hover effects on the dots change their fill color. The accompanying HTML provides a written analysis noting an overall upward trend in visitors between the two years, with notable increases in destinations like California, Hawaii, and Idaho.
