Inventions are important because they help humans survive. An invention is a new tool or process that serves a useful purpose or does that better than earlier inventions. Several related inventions often create a new technology (i.e. a set of tools, the knowledge to make such tools, and the infrastructure needed to maintain and use these tools).

Florence Nightingale is usually credited with inventing the polar area diagram, there are earlier uses. Léon Lalanne used a polar diagram to show the frequency of wind directions around compass points in 1843. André-Michel Guerry is an earlier inventor of the "rose diagram" form, in an 1829 paper showing frequency of events foAlthough Florence Nightingale is usually credited with this graphical invention, there are earlier uses.
