PART 1 :
Definitions
DATA,
NETWORKS,
ETC.
DATA :
- Factual information, especially information organized
for analysis or used to reason or make decisions
- Information output by a sensing device or organ that
includes both useful and irrelevant or redundant
information and must be processed to be meaningful
- Information in numerical form that can be digitally
transmitted or processed
From Merr iam-Webster
WHAT IS DATA?
Look at those
SOME
DATA
Written info in huge amounts
Quantification of its subject / object
Storage - in computers databases
Can be processed by machines
Huge trend in early 21st Century:
business, ad, indsutry, science, etc.
DATA=DIGITAL INFORMATION
Objectivize things to provide new understanding
A « facts are sacred » approach towards complex questions and problem-solving
Apply scientific method to interrogate any kind of beings, objects, ideas, etc.
WHAT IS AT STAKE WITH DATA?
HANDLE COMPLEXITY
Linked Data Cloud
Problem:
Most of data is made by machines,
for machines.
How can we access it?
How can we understand it?
HANDLE COMPLEXITY
1. Statistics: Studying
2. Data Munging: Suffering
3. Visualization: Storytelling
From raw data
to images

JOURNALISM
“The brain doesn’t just process information
that comes though the eyes. It also creates
mental visual images that allow us to
reason and plan actions that facilitate
survival.”

PART 2 :
WORKSHOP NETWORK MAPPING
The model of a network is everywhere :
cities, DNA, social relationships, Internet,
etc.
Question is : « What connects? » - and how.
What is this strange relationship that links
data to networks?
SURROUNDED BY NETWORKS
MAP THE CLASSROOM AS A NETWORK
WHAT CONNECTS IN THIS CLASSROOM?
Questions:
What is the structure of the network?
What are the different kinds of data we can identify?
How is the data produced? exchanged?
IDENTIFY A NETWORK
MAP YOUR OWN NETWORK !
Civil Society NGO-STK-Network Workshop in Istanbul by @graphcommons
Transmission Networks Something actually flows.
Interaction Networks Connection is an event, with a specific time.
Attribution Networks Connection is an expression of a relationship.
Affiliation Networks Connection is a belonging to a group or category.
CONNECTIONS
Objectives
Identify an interesting network related to a specific
territory
Ex: Food waste in Toulouse, actors in job research,
etc.
Deliveries
Draw an extensive map of this network
Use colors, dots, line, weight to represent things
MAP YOUR OWN NETWORKS
Where to start a graph?
You can start with the first thing that comes to your mind, then grow and tweak the map step by step from there.
Where to stop a graph?
Putting a definit ive graph title and considering only the strong connections help to limit your network map's scope.
Connection weight Strong connections bring closer the two end nodes, and reveal tight clusters. In fact, strong ties are more transitive than weak ties.
Collaborative mapping more fruitful and complete graphs, in fact, it is great for brain storming

National target
Cons
Nobody use this data
Unsustainable
Pros
Nice data platform
Rennes Collective Action
Citizen-based
No funding

METHODS VISUALIZATION
Objectives: extract, process, visualize, publish
Tools : Web-based, softwares, languages
WORKFLOW: CREATE A DATAVIZ
Ben Fry, Computational Design. 2004
A story tends to
1. begin somewhere
2. tell something
3. end.
These apply for a map, a graph, a visualization, etc.
You may find data in weird places.
Draft, draft, draft
Chose your tools based on your (team) skil ls.
Mind the time spent!
Be kind to your readers
DEFINE A DATAVIZ PROJECT
How it should work:
1. Define project
2. Find data
3. Draft something visual
4. Define tools & time
5. Clean and refine data
6. Visualize
7. Publish
8. Promote
How it really works
1. Great, I have some nice data/a bri l l iant idea !
2. Let’s try some tools
3. Well, I just waste 3 hours on tutorials
4. I should do something easier
5. Another 2 hours on google
6. What was this bri l l iant idea again?
7. I should post this l ink on Facebook
8. I t ’s late already. Let’s just forget about this dataviz thing….

WORKSHOP DATA STORYTELLING
IN PRACTICE
Based on your network map, imagine a specific story
you want to tell or a specific idea you want to
investigate with data.
A story
A title
A visualization draft
A list of possible data sources & how to get it Where to find interesting?
Can you access it? If not, imagine a way to get this data
Licensing, ownership & privacy issues
DESIGN A VISUALIZATION!
5 min Presentation
You have to put together a 5 min presentation
about your data story
You have to show:
A story
A title
A visualization draft
How do you plan to get your data?
(Some existing data, if possible)
YOUR DATA STORY
Pros
What is so great about
this presentation?
Cons
Why is this presentation
so awful?
COURT OF ATTENDEES
For each presentation, we split the attendees in 2 groups: pros & cons
The groups should change each time (one time pros, one time cons).
