That’s not very specific. Still, it’s not very hard. In SVG it’d be
<rect x="10%" y="10%" width="80%" height="80%" fill="black" />
Adjust the units/values to whatever pixel-perfect outcome you have in mind.

I’m not sure what “crossing” is supposed to mean, but:
<circle cx="50%" cy="50%" r="25%" fill="blue" />
> I want to draw some lines, cutting the circle.
<line x1="25%" y1="25%" x2="75%" y2="75%" stroke="white" stroke-width="4" />

This is beyond the ability of MacDraw, to the best of my recollection of
that app. What perhaps you mean instead is that you wanted to draw some
pie pieces that could fit together to make a circle. Easily done with
<path> elements, but you still have to supply the specific numbers you’re
looking to draw.
As I said, if you *really* want to do this, there are already web frameworks
out there that do most of it for you without having to do anything more than
supply the numbers.

Nothing is stopping you from doing those things.

So something like:
<image width="192" height="192" x="17" y="6" xlink:href="your_file.png”/>

Why? All that manual busy work in a GUI app just doesn’t make much sense.
I’d much rather find a way to give the computer the numbers and let *it* do
that tedious stuff.

Looked pretty easy on the Google framework I gave you the link for.

Such is the nature of many open source ports to the Mac. I myself have a
bit of a love/hate relationship with Audacity for that reason. These days,
my approach is use those apps on their native platform, either by running
a virtual machine on my Mac, or by installing them on a $100 Raspberry Pi.
If you’re expecting someone to write a Mac-specific app to do those
things, you have to make a better case than you’ve done here.
