This bar chart visualizes the relationship between daily water consumption and average sleep quality, with bars sorted by sleep quality in ascending order. The visualization uses D3.js v7 APIs including `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisBottom` to render the SVG chart. Data is loaded via `d3.tsv` from a remote CSV file, then processed with `d3.rollups` to group and average sleep quality by water consumption category. Interactive tooltips appear on hover, displaying the specific water consumption level and corresponding sleep quality score.
