This interactive bar chart displays malnutrition metrics across eight administrative blocks, letting users switch between height percentage, weight percentage, or their combined value, and filter by month (August, September, October). The visualization uses D3 v5 with SVG and animated transitions, employing `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the y-axis. Bars are colored with a sequential `d3.scaleSequential` interpolating through `d3.interpolateRdYlGn`. Tooltips appear on hover, and the data comes from external CSV files.
