Data Journalism : Notes & Advice

I attend a Guardian : Data Visualization Course

This is a summary of what I learn and what is best practise for data visualisation.

Follow @adamfrostuk @skelington @gDigitalAgency @guardianclasses or attend the course its excellent.

Data Visualization Process

Start with examining the data – are their outliers? is it accurate?

Data : Is it a credible and comprehensive dataset? Seek out interesting patterns and trends in the data. Use a web producer, data analyst or journalist. To produce integrity

Is this story important? What is the most important part to the audience link it into narrative.

Story : What does your audience care about? Find a story in the data that will resonate with your audience. Use a web producer, data analyst or journalist. To produce meaning.

Which chart will serve the story – is the chart making the story easier to understand. Bar chart are effective communicators.

Chart : Which charts will bring your story to life? Choose the best chart for your story. Use a data analyst or designer. Use Photoshop/Adobe Illustrator. To produce function.

Does your chart look good? If you graphic doesn’t look clear and engaging, then nobody’s going to look at it.

Design : Does your chart look good? Experiment with colour, space and text until the information is beautiful. Use a designer. Use Photoshop/Adobe Illustrator. To produce form.

 

Different Approaches – Tufte vs. McCandless

LOVE – Evidence (if you notice the chart first and not the data- then you have failed) vs. Information (apply graphic design principles to data journalism)

ROLE – Theorist (Universities orientated) vs. Practitioner (blog and produces informatics for journalism)

DISPLAY – Present all the data to show top-level trends vs. Selective use of data to guide reader to key story

ACCURACY – Never cheat data vs. Tweak visuals if it makes the story clearer

DESIGN – Design should be minimal or invisible vs. Design should be used to emphasis the story

PRIORITY – First loyalty is to data vs. First loyalty is to audience

FOLLOWERS – Loved by academics and statisticians vs. Loved by journalists and graphic designers

 

Deciding the story :

How do you decide when data will benefit from visual storytelling?

Quantity of data

More than one number, usually multivariate. Not just putting a number in a circle. comparison  / change / composition

Character or type of data

When visualising will speed up OR deepen understanding.

Building and structuring your story : What is a story?

Journalist : Who? What? Where? When? Why? How? (Supporting information then wider context)

Teacher : Bloom’s taxonomy: Key cognitive skills

  • Knowledge (give people basic facts and concepts)
  • Understand (help them to understand by organizing and comparing)
  • Apply (use these facts in new contexts and situations)
  • Analyse (identify causes/ motives, assemble evidence for these facts)
  • Evaluate (make judgements about whether the facts are valid)
  • Synthesize/Create (combine different sets of facts to form a new whole, or propose alternative facts).

Object-based learning. “Shared attention” theory of teaching/ storytelling.

Writer : Aristotle: exposition, rising action, climax, falling action or resolution, dénouemont

Christopher Booker’s seven stories

  • overcoming the monster (Jack and the Beanstalk, James Bond, Jaws)
  • rags to riches (Aladdin, Cinderella, David Copperfield)
  • the quest (Odyssey, Don Quixote, Lord of the Rings)
  • voyage and return (Alice in Wonderland, Peter Pan)
  • comedy (Twelfth Night, Pride and Prejudice)
  • tragedy (Faust, King Lear)
  • rebirth (Silas Marner, A Christmas Carol)

Emma Coats, Storyboard artist, Pixar: Once upon a time there was _____. Every day, _____. One day _____.   Because of that, _____. Because of that, _____. Until finally _____.

Salesperson : AIDA (Attention, Interest, Desire, Action)

  • Attention: The audience must be aware of what the product or service is.
  • Interest: Interest is generated by telling people more about the offering.
  • Desire: Desire is created – giving people an emotional response to the product.
  • Action: Audience are told what action to take if they want the product and/or audience takes this action.

 

Selection. Of all the possible stories there are, it is this story that is most relevant or interesting. Emphasis.  I’m now going to structure this story to emphasise this piece of information and then this and then this.

For infographics and charts: Selection. Of all the data there is, I am going to choose these datasets. Emphasis. I am going to emphasise this dataset as it is the most important. Then I’m going to emphasise this, and then this.

Great Examples

The True Size of Africa

Using data to tell a story

  1. Only visualise your data when it’s necessary. Sometimes the information is stronger as text.
  2. One story per chart/ infographic. Audience, medium and subject matter will determine the size and shape of your story.
  3. Only show data that supports this story. The Rule of Seven can be helpful here.
  4. Always show a key/legend. If you can, make your key part of the story.
  5. If your story has many chapters, then guide your reader through it.  Most important information first – so readers can take what they need. Be as concise as possible.
  6. If your chapter has many sections, then break it into manageable chunks. Think about how you memorise a phone number.

Design

Decide upon the look and functioning of (a building, garment, or other object), typically by making a detailed drawing of it.

Pattern perception & table lookup- Charts need to be showing the data and the insight

Clarity & persuasion- Good visual storytelling requires both at the same time

Legibility & readability- Text not only contains information but also structures it and aids reading

Consistency & contrast- Consistency aids reading and enables contrast for visual drama

Cause & Effect- The visual dramatisation of ‘therefore & however’

Data & visualisation- The data needs to be telling its own story

 

Interactive Storytelling

  • Subject matter predicates certain limits and constraints
  • Medium (e.g. software) establishes certain functional rules
  • Audience predicates certain requirements and priorities

1.Your interactive should have a single story or purpose.

2.Your interactive should tell a story before the user has clicked on anything.

3.Only use datasets that support your story or subject.
Remember every filter you add is asking your audience to make another choice.

4.Use drilldowns or the bottom part of the page to put secondary or contextual information.

5.Make it immediately obvious how the user can filter or reshape the interactive to tell their story.

6.If a key is required, make it dynamic or interactive too.

7.Remember users on mobiles and older browsers.
