# What is our project about again?
- Get **public opinion** polls where getting representative data from citizens is hard
- People responding with SMS to questions asked on radio show
- Africa's Voices:
- compiles, translates and aggregates responses
- uses that data to **inform policy makers**
- And we?
- **generate visualizations** that can help understand and
**explore** the obtained qualitative data

# We had a visit
- Week before last week Luke (our project partner) visited the Fachgebiet

# What we thought our goals were going to be
### Africa's Voices Researcher
Goal => Help to ease their process
1. Generate diagrams automatically.
2. Generate explorable diagrams.
3. Generate explorable diagrams to answer emerging questions.
### Africa's Voices Policy maker
Goal => Provide valuable information for decision making
{ style="float:right" alt="drawing" width="280"}
1. Build a tool to show data to policy makers.
2. Explore with policy maker / let policy maker explore.
3. Answer questions that emerge during exploration.

# What we think our goals are going to be now
0. **Understand** provided data / domain
1. **Brainstorm** / Design visualizations (a lot of them)
- Unconventional
- Explorable
- Individual-centered
- No completeness of data
2. **Implement** the best ideas
(3. Synthesize similarities into a framework)

# We have data
- Data privacy agreement
- Two files in JSON format
- Messages (1.2 GB)
- Individuals (1 GB)
- Each line in data files represents an individual/message => provenance
- Nested structure to show merge with other tracedata
- Objects contain:
- raw data (responses and personal information)
- coding of responses
- processing metadata
