A small multiple line chart shows monthly values for a single series across twelve months, with grey circles marking each data point. Hovering over a circle highlights it in red, brings it to the front, draws a dashed vertical guide line to the baseline, and animates a large value label near the point. Built with D3 v3, the visualization uses an ordinal x-scale for month names, a linear y-scale for values, and SVG paths, circles, and text elements. The data comes from a local JSON file with name, value, and date fields, parsed via `d3.time.format`.
