Tehtävä
Swipe to start coding
Build a line chart representing the level of CO2 emissions (metric tonnes of CO2 per person) for the US. Follow the next steps:
- Import the
matplotlib.pyplotunder thepltalias. - Save the
United Statesdata in theusavariable. - Create
FigureandAxesobjects using the.subplots()method ofpltand assign them to variablesfig, andax, respectively. - Initialize a line chart:
- display years on the x-axis (use the
.indexattribute), convert them to integers (int); - display level of emissions on the y-axis (use the
.valuesattribute).
- display years on the x-axis (use the
- Display the plot.
