How does it works?

Question

Hello 😊 I didn't really get how it works here.
I tried to create a circle in svg on my own to see functions of each attribute following the eg. , but I never succeed to make it appear.
This is what I figured :

1- Width and height create a box within which I can create the circle. But what does it stand for? It's not pixel, so what?

2-The cx and cy the position on the page. But in %, proportions...? I didn't get it at all.

This is the code I wrote before : can you see where is my mistake? Thanks 😊

<svg width="2000" height="2000">
<circle cx="90" cy"90"r="60" fill="green"/>
</svg>

Answer 1

You need to add space between cy attribute and r attribute.

Like, cy="90" r="60"

How, thanks. Searching for complicated things, I did not notice that 😅. I still didn't get how it works but it solved my problem.
