Every engineers knows the difference between a resistor and a capacitor on a schematic because there are a few agreed upon 'symbols' for these parts.
Creating a Symbol Outline/Shape
We can use the 'Wire' tool (which functions like the 'Line' tool that we used in the package editor) to draw a visual symbol for our part in the symbol editor.The GA1A1S202WP is an extremely basic IC, and doesn't really match an standard four pin symbol, so we can simply draw a box with the four pins sticking out of it for our schematic symbol, similar to the following:
