Data journalism in action: the London Olympics

People are obsessed with counting medals in the olympics. Mashing the data from the medal tally with other types of data like population or team size. They need something visual because of the popularity and how it needs to be easily understood. The ability to update the data visualisation is important in breaking stories so the audience can always be up to date with the latest data. As soon as you represent something in numbers everyone seems to have an opinion on it and it’s harder to guide the conversation.

The amount of similarities between journalism and data visualisation became apparent through the medal tally graph. The objective is the same, “To tell a story using numbers”.

The ability to engage and explore the data yourself through the interactive graphic data visualisations.

History of Data Journalism at The Guardian

Data journalism is something new and relies on the technologies of the moment. Since the very first issue of the Guardian in 1821 and have been presenting that data in interesting ways to bring the story to life.

The first table of data in the Guardian showcased information about the amount of kids in school at that time before compulsory education. Unless we understand and know whats going on in the world through data then how can things improve.

Before the guardian utilised photographs they represented visual data through graphs made up of type. The use of cross hatching and textures through lines to show different categories within the graphs. Moving from just stating facts to visually reassuring people through iconography and graphs. Photography and illustrations were then used to further add to the story as well as using the data. Interactions through digital maps and data visualised on computers allowed for speed and accessibility to data in the 21st century.

What is data journalism?

Before reporting was just about words but now it’s much more, its about telling a story through data. It is not just about obtaining the information it’s about what the data tells you. It lets you tell story in a way people will understand and enjoy it while also recognising the power of measurement in helping public conversation.

Data has become increasingly important because we have the tools to really analyse it and find patterns and trends.

“so what is data journalism? … It’s just journalism”

Visualisation Styles: Graphs

Why do we use graphs?

“To make comparisons easier.”

Overuse of bubble charts. This chart show the world’s biggest banks and their capitalization from 2007 to 2009. The data shows how the capitalization has decreased over the two year period through the light and dark green areas of the bubbles.

Screen Shot 2016-08-09 at 2.09.58 PM.png

The comparisons of the bubble chart and the bar chart shows how inaccurate bubble charts can be. Our brains think that the dark green bubble shows a 50% decrease but when the same data is shown in the form of a bar chart we can see how it actually about 1/3.

(Circle vs. Squares.)Screen Shot 2016-08-09 at 2.13.37 PM.pngSquares are easier to compare than circles.

The use of colours and shading to represent heigh in a map is successful because there are more important things on the map that the reader needs to focus on. The bar graph in the top right shows data in a more accurate way, comparing the two data sets to clearly show the meaning extracted. On the scale, colours and shading is considered less accurate while position comparisons are more accurate (bar graphs etc).

Three most common charts.

Bar charts are useful and easy to use and are widely known. It makes it quick to compare info especially when using numbers.

Line charts are as popular as bar charts, they conenct individual numeric data points. Simple way to visualise a sequence of values and to display trends over time.

Pie charts are used to show the relative proportions of information.

Reflection

Different graphs are used to show different types of information and data, if used incorrectly the information becomes blurred to the viewer.

  • Temperature is also shown by vertical lines.
  • Reduces the time to understand the data.

  • War between Russia and England.
  • 6 Months to get access to medicine.
  • Soldiers were dying and wanted to improve the lives of soldiers.

  • Graphing the causes of death during the war.
  • The real threat was disease to the soldiers.
  • Shows comparison of two years for each graph.
  • Made through area, the smaller numbers in the middle to at least be visible.
  • Visually show the impact over a period of time.

  • Make issues understandable for the uneducated through visual education.
  • Popularised multiples of something to equal something greater.
  • Bringing the museum to the people, to distribute ideas.

Using visual education to transform the masses.

Part 2:

Why visualise?

Help us understand complex data and see the trends that are not able to be seen with lots of numbers. Through the use visuals the understanding is made clearer and faster.

Screen Shot 2016-08-09 at 1.52.09 PM.png(Raw data: too much information for the viewer to decode)

Screen Shot 2016-08-09 at 1.54.18 PM.png
(Useless visualisation when the software export the data into a graph.)

  • Use visualisations to convince the audience of the message or claim the data is making.
  • Let the audience extract their own meaning.

 

 

 

 

Data Types

There are different levels of measurements when it comes to types of data, these include nominal, ordinal, interval and ration. It is important to know the difference between these data types as to prevent communication mistakes when presenting data.

Nominal data is a type of data that has a list of name and is unordered.nominal.png

Ordinal data refers to data that is ordered in some way.ordinal.png

Interval data is numeric in value and the exact differences as well as the order are known.Screen Shot 2016-08-03 at 10.27.21 AM.png

Ratio is also numeric but the difference between interval and ration is that the 0 has value.

Reflection

In order for the audience to understand the data more clearly the right type of data type must be used to relay the information in order to not make any communication errors.

Introduction to Data Visualisation: Infographics and Data Visualisation

What is data?

Data is an essential part of communication and is the result of of measurements and can be quantified through either qualitative and quantitative data and can be visualised through graphs and/or images. In order for the user to understand the information within the data the data must be interpreted and take on a meaning.

What is data visualisation?

Data visualisation is the study and creation of the visual representation of data which is the modern reflection of visual communication. In order for a data visualisation to be successful it needs to clear and efficient using statistical graphs, plots and info-graphics.

Difference between information graphics and data visualisations.

  • Not all information visualisations are based on data but all data visualisations are information visualisations. Efficient visualisations help the user analyse the data and makes the complex data more easy to understand.

  • Showcases how info graphics aren’t data visualisations because of the lack of quantifiable data.

Reflection

Data visualisation is an important aspect of communication as it can help us understand complex data more easily. The world is becoming more and more rich with data so the creation of efficient visualisation is important in the consumption of data.

The model has 4 key models and 4 key components these components include visualisation, story telling. interactivity and shareability. The four models are The watercooler, the cafe, the research library and the lab.
