1. Chapter 1
Introducing Data
Storytelling
A quick overview of the
essentials of data
storytelling, its tools,
and applications.

2. Introduction
Data storytelling is
crucial for effectively
communicating insights.
– combines data
science with
narrative
techniques to make
data relatable.

• Data storytelling
– turns raw data into engaging
narratives.
– Moves from data exploration to
presentation.
– Focuses on relatable stories to
help audiences make informed
decisions.

4. Tools for Data Storytelling

– A declarative library
simplifying
visualization.
• Generative AI:
– Tools like ChatGPT,
DALL-E, and GitHub
Copilot aid in text,
images, and code.
import altair as alt
import pandas as pd
df = pd.DataFrame({
'x': [1, 2, 3, 4, 5],
'y': [1, 4, 9, 16, 25]
})
chart = alt.Chart(df
).mark_line(
).encode(
x='x',
y='y'
).properties(
title='Square Numbers'
)
chart.save(‘chart.png’)

5. The DIKW Pyramid
• The DIKW Pyramid guides
data storytelling.
• Helps to structure data
stories from raw data to
actionable insights.
• Each step transforms
data, adding context,
knowledge, and wisdom.

6. Key Takeaways
• Data storytelling combines art and science, encouraging
audience action.
• Shifts the focus from the data scientist’s perspective to
audience interests.
• Python Altair and Generative AI enhance the storytelling
process.
• The DIKW Pyramid structures data, making it actionable
and impactful.
