What is the process called when a diagram or graph is created using appropriate tools like a ruler and pencil?

The process of creating a diagram or graph using tools like a ruler and pencil is accurately referred to as drawing. This term encompasses the precision and skill involved in accurately representing data or concepts on paper. Drawing is a method that ensures clarity and accuracy in the representation, which is essential in any scientific or mathematical context where visual communication plays a crucial role.

In this context, sketching generally implies a more informal representation that might not emphasize precision as much, while mapping often refers specifically to the representation of geographical areas or data distribution. Rendering typically involves adding details or artistic elements to a drawing, which goes beyond the basic creation of diagrams or graphs. Therefore, the act of using precise tools to create a clear representation aligns with the concept of drawing.
