What is the low, medium, and good range of text to HTML ration on webpage?

If I am creating or maintaining a website so for the SEO or page experience point of view:

  1. What memory size of text will be comparable to HTML code (for example: text should be 52kb and HTML should be 100kb or vice versa)
  2. Or how much characters will be measurable low, medium, and good compare to HTML code (for example: text should be 250 words and HTML code should be 500 words or vice versa)

Cannot get aspect ration to 1 with simple Graphics

I am learning Mathematica and doing a simple animation project which animates the harmonic motion of a pendulum. For some reason, I cannot get the simplest thing to work — the aspect ratio for my pendulum graph will not go to 1. I have whittled my code down to something extremely simple that illustrates my problem:

Graphics[Line[{{0, 0}, {.5, -.5}}], Axes -> True, PlotRange -> {{-1.1, 1.1}, {-1.1, 0}}, AspectRatio -> 1]

Output of the code above
