One way to collapse the graph of a scalar-valued function of two variables into a two-dimensional plot is through level curves. A level curve of a function f(x, y) f (x, y) is the curve of points (x, y) (x, y) where f(x, y) f (x, y) is some constant value.

- Line Graphs. A line chart graphically displays data that changes continuously over time. Each line graph consists of points that connect data to show a trend (continuous change).
- Bar Charts. Bar charts represent categorical data with rectangular bars (to understand what is categorical data see categorical data examples). Bar graphs are among the most popular types of graphs and charts in economics, statistics, marketing, and visualization in digital customer experience.
- Pie Charts. When it comes to statistical types of graphs and charts, the pie chart (or the circle chart) has a crucial place and meaning. It displays data and statistics in an easy-to-understand ‘pie-slice’ format and illustrates numerical proportion.

There is a close relationship between level curves (also called contour curves or isolines) and the gradient vectors of a curve. Indeed, the two are everywhere perpendicular. This handout is going to explore the relationship between isolines and gradients to help us understand the shape of functions in three dimensions.
