This example shows a line chart of stock closing prices over time, with interactive data points that reveal a tooltip containing a hyperlink on hover. Built with d3.js v4, the visualization uses `d3.csv` to load the data, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.line` for the path. The tooltip, styled with CSS, is rendered via `div.html` and includes an anchor tag linking to an external site, with its position set using `d3.event.pageX` and `d3.event.pageY`. SVG circles mark each data point.

AI-generated description

This is a simple graph demonstrating the addition of tooltips with a hyperlink in a graph. This was written using d3.js v4 and is a follow on to the simple scatter plot example with tooltips here.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 4 of d3.js.
