Code example: parsing and plotting

This example assumes a little bit of experience with established tools from the Python ecosystem.

Create a file called plot.py:

import sys
import pandas as pd
import matplotlib.pyplot as plt
plt.style.use("ggplot")

df = pd.read_csv(
    sys.argv[1],
    index_col=["time_iso8601"],
    parse_dates=["time_iso8601"],
    date_parser=lambda col: pd.to_datetime(col, utc=True),
)
df.index.name = "time"

df["DE-BW"].plot(
    title="DE-BW confirmed cases (RKI data)", marker="x", grid=True, figsize=[12, 9]
)
plt.tight_layout()
plt.savefig("bw_cases_over_time.png", dpi=70)

Run it, provide cases-rki-by-state.csv as an argument:

python plot.py cases-rki-by-state.csv

This creates a file bw_cases_over_time.png which may look like the following:
