This line chart visualizes the estimated number of honey bee colonies starting each quarter in the United States from 2015 to 2021, based on data from a CSV file. The chart uses `d3.scaleBand` for the year-quarter x-axis and `d3.scaleLinear` for the y-axis, with tick labels formatted in thousands. A single `path` element is drawn using `d3.line()` to connect the data points, while circles mark each observation. The SVG rendering includes custom styling for axes, labels, and interactive hover effects on the dots.
