This radial bar chart visualizes monthly household electricity consumption in kilowatt-hours (kWh) for a single year, with each month represented as an arc whose angular length is proportional to its consumption value. The visualization uses D3 v4 to render an SVG, animating the arcs' growth on load via a `transition.attrTween`. Data is loaded from a local CSV file using `d3.csv`. Hovering over an arc reveals the exact value via a tooltip, and the chart includes radial gridlines and axis labels to aid reading the scale.
