This interactive bar chart visualizes the quality ratings of red and white wines, showing how various chemical attributes like acidity, alcohol, and pH compare across quality scores. A dropdown menu, built with the `dropdown_menu` module, lets users switch between white and red wine datasets and select which chemical attribute to display on the y-axis. The chart, rendered as SVG using D3 v5, animates bar transitions with `transition().duration(1000)` when selections change, sorting bars by quality and updating axes, labels, and the title dynamically. Data originates from a CSV file of wine properties.
