The below graph illustrates the relationship between the level curves and the graph of the function. The key point is that a level curve $f(x,y)=c$ can be thought of as a horizontal slice of the graph at height $z=c$.

This is a figure-level function for visualizing statistical relationships using two common approaches: scatter plots and line plots. relplot() combines a FacetGrid with one of two axes-level functions: scatterplot() (with kind="scatter"; the default) lineplot() (with kind="line")
. A bar chart should be used if the independent variable is. categoric. . Discrete. or categoric data can also be shown on a pie chart. Pie charts are often used when using percentages of data to...
Recall from Section 15.1 that the curve. f(x,y)=. z. 0. , where. z. 0. is a constant, is a level curve, on which function values are constant. Combining these two observations, we conclude that the gradient.
Level curves of the function g(x,y)=√9−x2−y2 g (x y) = 9 − x 2 − y 2, using c=0,1,2 c = 0 1, 2, and 3 3 (c=3 c = 3 corresponds to the origin). A graph of the various level curves of a function is called a contour map.
A scatter plot is a visualization of the relationship between two quantitative sets of data. The scatter plot is created by turning the datasets into ordered pairs: the first coordinate contains data values from the explanatory dataset, and the second coordinate contains the corresponding data values from the response dataset.

Why are level curves important?
Level curves are the curves on a graph representing all points where a multivariable function has the same constant value. These curves provide insight into the behavior of functions with two variables by visually depicting how the output value changes with different combinations of input values, and they help to analyze critical points ...
