The required graph for a single variable is a linear graph or time series graph
<h3>Single variable graph</h3>
A single variable graph is a graph having an input and one output.
For instance, the equation of a line y = mx + b is a single variable graph.
Hence the type of data for a single variable graph will give a linear function. Therefore the required graph for a single variable is a linear graph or time series graph
