6. What is:
Data science Graph data science
Data science is an
interdisciplinary field
that uses scientific
methods, processes,
algorithms and
systems to extract
knowledge and insights
from structured and
unstructured data.
Graph Data Science is a
science-driven
approach to gain
knowledge from the
relationships and
structures in data,
typically to power
predictions.
Data scientists use data to answer
questions.
Data scientists use relationships to
answer questions.

Data science: it’s complicated
Dozens of
libraries,
hundreds of algos
& no docs!
How do we
shape data into a
graph in the first
place?
We’ve picked a
library...good

What? We have
to build the
entire ETL pipeline
for this?
Are the results
