This area chart visualizes the relationship between sleep hours and age, plotting age on the y-axis against sleep hours on the x-axis for a dataset loaded from a CSV file. The chart uses D3 v6 with a linear scale for both axes, an area path filled in steelblue with semi-transparency, and a monotone curve for smooth transitions. Data points are parsed from the CSV columns "SLEEP HOURS" and "AGE", and the SVG rendering includes bottom and left axes.
