Use wget to mirror a single page and its visible dependencies (images, styles)

Graphic via State of Florida CFO Vendor Payment Search (flair.myfloridacfo.com)

This is a quick command I use to snapshot webpages that have a fun image I want to keep for my own collection of WTFViz. Why not just right-click and save the image? Oftentimes, the webpage in which the image is embedded contains necessary context, such as captions and links to important documentation just incase you forget what exactly that fun graphic was trying to explain.
