Understanding game review

Hi everyone,
I'm trying to understand the features of game analysis better. For example, I’m curious about:

• What does "depth" refer to?
• What does the line chart represent?
• What does "accuracy" mean, how is it calculated, and how does it vary with player levels?
• What is "game rating," and why does it seem higher than my ELO?

If you have answers to these questions or can recommend a video tutorial, I’d really appreciate it!

Depth refers to how deep the engine is analyzing in ply (half moves). The more dept the more accurate is the engines evaluations.

The chart shows who had the best position during all the moves of the game.

Accuracy try to measure how well the players played. The lesser amount of mistakes the higher accuracy. Chess.com has its own way of calculating this, and I don't think they has revealed it in details.

Game rating is just a gimmic. Try to ignore it unless it makes you happy.
