Question

old faithful eruptions
what type of graph is being shown?
line
scatterplot
circle

Explanation:

A scatterplot is a type of graph that uses dots to represent the values of two different variables. In this graph, each dot represents a data point with one variable being the "eruption duration (min)" and the other being the "waiting time between eruptions (min)". A line graph typically connects points with straight - line segments to show trends over a continuous variable (often time). A circle graph (pie chart) is used to show proportions of a whole. A bar graph uses bars to represent data, usually for categorical or discrete data.
