This bar chart displays the relationship between daily water consumption and average sleep quality, with a dropdown filter for gender and the "7-10 cups" category excluded. The visualization renders aggregated data using SVG and D3 v7 modules, including `scaleBand`, `scaleLinear`, and `axisBottom`. Bars are interactive, showing a tooltip on hover and changing color, while the data is sourced from a TSV file processed with `rollups` and `mean` from `d3-array`.
