simple line chart from dataset
A simple line chart plots twelve monthly values from a small JSON dataset, with a gray circle for each point and a black polyline connecting them. Hovering a circle turns it red, enlarges it, and increases the font size of the corresponding month label and the final value annotation. Built with D3 v3, the chart uses an ordinal x-scale and linear y-scale, `d3.svg.line` for the path geometry, and `d3.select` with event handlers for interactive feedback.
