I see a  typical "caricature" drawing representative of a grown woman throwing a temper tantrum like a three-year-old.  This drawing is accurate IMO.

A caricature is a rendered image showing the features of its subject in a simplified or exaggerated way through sketching, pencil strokes, or through other artistic drawings.

In literature, a caricature is a description of a person using exaggeration of some characteristics and oversimplification of others.^[1]

Caricatures can be insulting or complimentary and can serve a political purpose or be drawn solely for entertainment. Caricatures of politicians are commonly used in editorial cartoons, while caricatures of movie stars are often found in entertainment magazines.  https://en.wikipedia.org/wiki/Caricature

Caricatures are generally unflattering. She did have a temper tantrum. Several tennis players have chimed in about 'this incident' including John McEnroe, the king of tantrums, along with Martina Navratilova, Chris Everett and several other professional players. There is a WHOLE lot more to this than just a temper tantrum. Were any of you watching the match? I was and I'm torn about both the decision and the cartoon.

"I'm torn about both the decision (by the umpire) and the cartoon". Not a word uttered by me about stats or who was the best player. There WERE some words from other tennis players who know lots more about tennis and penalty calls than I do.

....from my perspective: no

....was her opponent blonde ?

All of her features are exagerated in a most unflattering way. I’m not that familiar with ms Williams so the drawing makes a negative impression on me. I see a woman throwing a fit and the woman apparently lost as she’s jumping on her racket. It could be considered racist if the viewer is over sensitive. My guess is Williams is black, has prominent lips and overweight though I doubt the latter as she must be an athlete.....

She's a big boned very muscular woman. My ex- would say, she's a Brick House.

I see it as a caricature, which tend to be unflattering. Seeing the photo added to Julie's answer clarifies the clothing in the cartoon.

If you want to see racism, by golly, you'll see it. I don't. 

No!

Nope

No , she's just someone who's used to being the centre of attention having a tantrum.

I don't see how it's racist, but I don't know why they had to make her look so fat.

The arm in the drawing is fit and tone instead of loose and flabby. Having seen Serena several times previously, I did not see the drawing depicting her as fat. (The only fat I'm seeing is a woman throwing a Big Fat Tantrum). LOL

It's not racist, it's just that she looks rather manly. Crocodile Dundee might have been confused. "Manly, yes, but I like it too." Serena, not the soap. (LOL)! https://www.youtube.com/watch?v=QtdEDaa3aW0

No.  I do not think it was racist.  But the words about her being upset because she lost seems ridiculous.  I think she was upset because of differential treatment.  Wanting to penalize her for something that they don't penalize men for.  But often that is the name of the game.

Exactly my point also. Male tennis players made the same observation and stated so. I guess we all hear just what suits our ears. :((
