Title: It tells us about the data for which the graph is drawn.

X-axis: It tells us about the label on the x-axis, which is the time interval (days of week in the above example).

Y-axis: It tells us about the label on the y-axis, which is the quantity (muffins sold in the above example).

Scales: The horizontal and vertical scales tell us the quantitative value of “how much” or “how many”.

Points: It represents the (x, y) ordered pair.

In the given figure, the point represents that five muffins were sold on Monday.

Trend: You need to connect the points to make the graph. The meeting point of the label on the x-axis and y-axis reveals the movement.
