JMP is a "Data Discovery" tool from SAS Institute. It is used for combining advanced data visualization techniques with powerful statistical tools.
JMP is a software product offered by SAS Institute that, in contrast to base SAS software, is focused on data visualization. While it has much of the same statistical power of SAS and is easily linked to various SAS products, its focus is on the visual. Producing graphs easily that allow you to see trends in your data, it complements the more numbers-focused base SAS offering and is used across all major industries.
JMP is pronounced "Jump", intended to evoke the idea of making a 'jump' in understanding by seeing your data in a visual manner.
