Plotly + Matplotlib

Plotly + Matplotlib is for charts/tables. Matplotlib/Plotly draw graphs. pandas holds tables (DataFrame). In interviews, say: DataFrame = rows+columns, then plot one column.

Tiny mental example: marks = {"Asha": 90, "Ravi": 85} → bar chart. You don’t need a PNG on the theory page — know the pipeline: data → figure → show/save.

Plotly + Matplotlib — output — [('Asha', 90), ('Ravi', 85)]. That data is what you plot.

Exam tip

Pipeline in three words + one library name.

Example

# Plotly + Matplotlib
xs, ys = ["Asha", "Ravi"], [90, 85]
print(list(zip(xs, ys)))
# matplotlib: plt.bar(xs, ys); plt.show()

Plotly + Matplotlib — output: [('Asha', 90), ('Ravi', 85)]. That data is what you plot.
