There are two major types of builtin plotting functions:

Plotting Math Functions

Note, most plotting function's names contains the word “Plot”, but not all. For example BarChart, PieChart, Histogram, BoxWhiskerChart, etc.

To get a list of builtin functions for plotting, type any one of the following to get a list:

or see

for example:

WolframLang Plot3D 2022-02-09 gdYC
Plot3D[ Sin[x] Sin[y], {x,0,10}, {y,0,10} ]

Functions for Data Visualization

example

WolframLang PieChart3D 2022-02-09 q74Z
PieChart3D[{3, 10, 1}, ChartLabels -> {"a", "b", "c"}]

Options for Plot Functions

Type Options[ FunctionName ] to get a list of options for the function. Example:

Commonly Used Options for 2D Graphics

Commonly Used Options for 3D Graphics

Commonly used options for 3d plot functions that plots surface of math function. For example: Plot3D, ParametricPlot3D

example:

ParametricPlot3D[
{Cos[u]*(2 + Cos[v]), Sin[u]*(2 + Cos[v]), Sin[v]} ,
{u, 0, 5},
{v, 0, 6},
 PlotPoints -> 100,
 Axes -> False,
 Boxed -> False,
 BoundaryStyle -> Directive[Black, Thin],
 PlotStyle -> Directive[White, Opacity[0.7], Specularity[10, 20]],
 Lighting -> "Neutral"]

How Does WolframLang Graphics Work

All WolframLang graphics is a expression that's a list of graphics primitives.

All Plot functions or visualization functions that show graphics, are internally creating a list of graphics primitives.

graphics primitive

graphics primitive is a expression that represents a graphical element, such as line, circle, polygon, text, sphere, tube.

some graphics primitives are 2D (such as Circle, Disk, Rectangle), some are 3D (e.g. Sphere, Cuboid, Tube), some both (e.g. Point, Line, Polygon).

Example of graphics primitives:

Complete list at SymbolicGraphicsLanguage

Graphics primitives are symbolic. By themselves they do nothing.

Displaying Graphics Primitives

To display a graphics primitives, such as Line[{point1, point2}], put them inside the functions Graphics or Graphics3D.

Example

WolframLang Graphics 2022-02-09 f3D4
Graphics[Line[{{0, 0}, {2, 1}}]]
Cuboid 2022-02-09 5g87
Graphics3D[Cuboid[{0, 0, 0}, {1, 2, 1}], Axes -> True]
WolframLang cubes 2022-02-09 mJgr
Graphics3D[Table[Cuboid[{x, x, x}, {x, x, x} + 1], {x, 0, 5}], Axes -> True]

Discretize Graphics

DiscretizeGraphics and DiscretizeRegion returns a MeshRegion. These are critical, when you want to do a transformation on graphics, so that it is applied all points on edge or faces, instead of just on vertexes.
