interactive line chart from dataset
This interactive line chart visualizes a time series of monthly values from a small JSON dataset, plotting seven data points with circles connected by a black line. Hovering over a circle highlights it in red, reveals a dashed vertical guideline from the point to the baseline, and displays the exact value as text. The chart uses D3 v4 with SVG rendering, employing `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, and `d3.timeParse` for date handling. Mouseover and mouseout events control opacity for the guide lines and value labels.
