Multi-links in tooltips using v4
This example shows a line chart of stock closing prices over time, where each data point is a circle that reveals a tooltip on mouseover. The tooltip displays the formatted date and price, and the date itself is wrapped in a hyperlink that points to a different URL from the CSV data. The visualization is built with D3 v4, using SVG for rendering and transitions for tooltip opacity. Data is loaded from a CSV file with `d3.csv`, dates are parsed with `d3.timeParse`, and the axes are generated with `d3.axisBottom` and `d3.axisLeft`.
