autosomal DNA - basic questions

my apologies if this had been previously asked and answered - I did not see it.

the graphic I see when I look at the chromosome browser page shows a bar for each chromosome. The length of the bar decreases from top (chromosome no. 1) to the bottom (chromosome no. 22).

Does the length of the bar represent the actual length of each chromosome?

Is there a grand design by which the number assigned to each chromosome corresponds to its length?

Each bar has a notch. What does the notch represent?

thanks for helping me understand the basics - Dwight Hogge
