Dynamically generated graphics
Explanation:
The term "Dynamic generated graphic" refers to simulate movement, motion, or generating a specific environment using the computer. It can also be thought of as multiple plots associated with time. Hence the graphics generated in the dynamic manner from the real time data utilize the huge part of the CPU cycles.

Answer: No
As we have 2 == operators, so they are executed from left to right.
a == b == c
⇒ (a == b) == c
⇒ (10 == 10) == 10
⇒ true == 10
⇒ 1 == 10
⇒ false
Why is true converted to 1?
The rule for == says if one of the operands is boolean, it's converted to number before the comparison.
true is converted to its number value, which is 1.

Dear Community,
It's become challenging to balance content creation alongside my full-time job and creation of app that will give you any course for free - I am working on that after work for previous 8 months).
This is why I've assembled a team (15 people atm) to help. They're compensated from my own pocket, so I decided to occasionally post some ads to at least reduce the costs of maintaining our community a little bit.
Rest assured, any ads will be clearly labeled, and I'll give my best to filter out any scams.
Thank you for your support and understanding!
For any questions feel free to contact me directly at @mldatascientist
Warm regards,
