S-curve
Winding road section
An S-curve is a line that bends in two directions, forming the shape of the letter S.
In graphs, S-curves show growth that starts slow, accelerates sharply, then levels off—common in adoption of new technologies, population growth, and learning.
The shape appears in design, roads, and body contours: The path followed an S-curve through the garden.
