The spinorama is the default standard display for anechoic loudspeaker data.

Evidence

With comprehensive and accurate anechoic measurement data, consumers who can interpret the curves are informed about the potential sound quality of loudspeakers without hearing them. It is a skill worth acquiring as online purchasing is the new norm. As can already be seen, this book will help consumers to “read” the information in the spinoramas. It is an “analog” skill; neither mathematics nor an engineering degree is required. — Toole, Floyd E, Sound reproduction- the acoustics and…, 250 (#expands, via linked claim)
