26. Data Analytics - Share Data Through the Art of Visualization - Week 3
Learning storytelling with data. Stories make people care.
For a story to be successful, focus on who is listening.
Stay on track with your key message.
Ask self: What's the single most important thing I want my audience to learn from my analysis?
Definitions:
Data visualization // the representation and presentation of data to help with understanding
Dashboard // tool that organizes information from multiple datasets into one central location for tracking, analysis, and simple visualization
Dashboard filter // a tool for showing only the data that meets a specific criteria while hiding the rest
Data storytelling // communicating the meaning of a dataset with visuals and a narrative that are customized for each particular audience
Engagement // capturing and holding someone's interest and attention
Spotlighting // scanning through data to quickly identify the most important insights
Filtering // showing only the data that meets a specific criteria while hiding the rest
Theme // a preset of colors, formatting, and other elements of visualization that is consistent throughout the visualizations
Creating a narrative slideshow:
- Pick a theme, add text, visuals, the big reveal at the end, paste/link/embed data
- Create screenshots in Tableau by exporting as image, PDF, Powerpoint, etc.
- Create presentation
- Limit a slide with 25 words or less
- To avoid editing original data, copy/paste, or embed data.
Narrative you share needs:
- Characters // people affected by your story
- Setting // describes whats going, how often, what task are involved, and the background info
- Plot // the conflict, the tension, the complication that your analysis is trying to solve
- Big Reveal // the resolution. show the characters how the data shown can solve the problems
- Aha Moment // when you share your recommendation and explain why itll help success
Editing Dashboards:
- Changing boxes to Floating allows them to hover above other boxes.
Filters:
- Help remove outliers from a dataset visualization so that the focus can be put on the main story.
Live vs Static Insights:
Live:
- Pros: dynamic, scalable, up-to-date, allows immediate action, alleviate time on processes
- Cons: takes engineering resources to maintain live and scalable, can't control narrative of
data, can cause lack of trust if data isn't handled properly.
Static:
- Pros: tightly control point in time narrative of data and insight, allows complex analysis
- Cons: insight's value degrades as long as data remain in static state
3 Data Storytelling Steps:
1. Engage your audience // make the story meaningful to the audience, make them engaged
2. Create compelling visuals // show the story of your data
3. Tell the story in an interesting narrative // connect data to project's objective and explain it
clearly
Effective Data Stories:
- Setting the context // does visualization clarify the data? does it help set the context?
- Analyzing the variables // does visualization help clarify the data variables? meet 5 second rule?
- Drawing conclusions // does visualization help make a point? clarify data?
Understand the audiences POV:
- what role does this audience play?
- what is their stake in the project?
- what do they hope to get from the data insights I deliver?
