Dots

Let us start off with the most basic of this basic command: drawing a dot.

To draw a dot, simply write the following code:

dot((0,0));

$[asy] dot((0,0)); [/asy]$

You can fix certain attributes to this dot, such as color:

dot((0,0),green);

$[asy] dot((0,0),green); [/asy]$

Circles

In this article, draw(circle((0,0),5));

We see that the first draw() command creates the circle, which uses the circle() command. How this works is that the circle() command produces a path in which the draw() command draws. Within the circle command, we see the center point is located at the cartesian plane point (0,0), and it has a radius of 5.

This code produces:

$[asy] draw(circle((0,0),5)); [/asy]$

Once again, we can fix certain attributes to this code:

draw(circle((0,0),5),red+linewidth(1));

$[asy] draw(circle((0,0),5),red+linewidth(1)); [/asy]$

And we can fill the inside:

filldraw(circle((0,0),5),green,red+linewidth(1));

$[asy] filldraw(circle((0,0),5),green,red+linewidth(1)); [/asy]$

Ellipse

Another rounded figure we can create is the ellipse.

draw(ellipse((0,0),5,3));

In this case, the (0,0) is the center of the ellipse, the 5 is the length of the major axis and the 3 is the length of the minor axis. This results in:

$[asy] draw(ellipse((0,0),5,3)); [/asy]$

Once again, we can fix attributes and fill the inside.

$[asy] filldraw(ellipse((0,0),5,3),green,red+linewidth(1)); [/asy]$
