We have electronics that can do a multitude of incredible things. I understand that data has to do with the binary system, but I can’t get my head around how electricity can be transfered into data… and how that data can then generate images and render graphics, etc. I mean, wut!? Plz hlp, brain cannot compute.

Electricity travels really fast. If I flip a light switch to make a connection, the lightbulb will have electricity flowing through it basically instantly, no matter how far away it is from the switch. However, all you can do is change whether the light is on or off; there’s no dimmer switch.
So say you wanted to send someone far away the text of the alphabet: “ABCDEFG…” You have a switch and the other person is looking at the lightbulb it’s connected to. Ahead of time, you would agree with the person that a certain pattern of on/off by the light means the letter “A”. A different pattern would mean “B”, and so on. It’s like Morse code. You can send a message by manually flicking the switch on/off; this is basically what a telegram was. However, that’s really slow. Eventually, we built machines that can flip a switch billions of times per second and can read the on/off signals coming in that fast and translate them back into text for us. The rest is translating that text into instructions for machines. Like every time your monitor refreshes (60+ times per second), your computer has to send it a list of instructions: “Row 1, column 1: turn on the lights to color this pixel white. Row 2, column 1: turn on the right lights to color this pixel black…” and so on.
