Axis
A line on a graph that's not parallel to the y-axis, but not because it's trying, it's just really, really close. Like that one friend who insists on standing right next to you at the party.
Chart
A fancy word for "table", but without the "table" part, because, you know, that's not as cool.
Curve
A mathematical function that's like that one friend who's always trying to get your attention, but never quite reaches it.
Graph
A 2D or 3D representation of data, because who needs more than two dimensions, really?
Metric
A way to measure things, but let's be real, it's just a fancy word for "boring unit of measurement".
