The process of creating a visual representation of data or mathematical relationships, typically on a coordinate system or diagram.
From graph (Greek graphein 'to write/draw') plus -ing suffix. Graph became a standalone word in mathematics in the late 19th century from German 'Graphik'.
Graphing might seem like just a math skill, but it's actually how scientists discovered gravitational waves and found water on Mars — visualizing data reveals patterns invisible in numbers alone!
