Iniport pandas as od

path $=\frac{.}{.}$dat$\frac{o}{s}$egents.$csv$

seg$=pd.rea{d}_{c}sv(path)$

the path variable creates a new dataframe called 'segments' which can now be populated with data

None

It creates a chart of data in the segments format

It provides a path to the data table called 'segments' that can be used later
