This visualization shows the population of Texas over time using a combined line and area chart, highlighting trends with a smooth curve. It loads data from a CSV file and renders an SVG graphic using D3 v5. The code uses `scaleLinear` and `scaleTime` for axes, `line` and `area` generators with `curveBasis`, and `axisBottom` and `axisLeft` for tick marks. The area is filled pink, with an orange and green axis styling.
