This week class activity was based on Data Visualisation.
The brief for this activity required from as to separate into groups and each group had to create a 3D set of data that was going to represent a topic form our everyday life.
The topics were spread into the class randomly. Our topic was FOOD AND DRINK.
The first thing that we did was to write down a few ideas that we could collect data from,and that the data that could collect was going to be interesting.
After a discussion we ended up with the idea of “What are the drinks we consume more in our country”.
The next step was to create a bar chart that was presenting how many cups/glasses of hot drinks, alcoholic drinks, Water and soft drinks we, ourselves, usually consume in our country in a week.
After collecting all the necessary data, we chose some materials that were provided to us from our tutors and we went to the canteen in order to find more stuff that we needed so as to complete our 3D set of data.
The materials that we used were plastic glasses, coffee as a representation for hot drinks, water for water, apple juice for alcoholic drinks and a red energy drink to represent the soft drinks.
Below you will find pictures that will show to you each step that we took for our journey until to create our 3D Data representation.
In nowadays, huge amounts of information are spreading outside to the world. They bombard us with information every minute.
But who wants to sit and read long articles with text-based content?
A lot of us, even if we are interested to learn new things, reading a text-based content, at some point we might get bored.
And here is where Data visualization comes in order to give to these articles a stimulating form.
What is data visualization?
Data visualization is a way to present information in a pictorial or graphical format.
Visual representations are easier to be understood by people. The reason is because the human brain uses a tactic to process the information that are given to us, which that make us to be able to understand easier and absorb faster the information that are given to us in the form of a visual representation.
Articles that are presenting their data in a visual form, for example in charts and graphs would be understood by the public faster and will get the meaning of the data that is present faster that if they were going to read a text-based document.
Below you will find a video that is part of the UBC Learning Commons and is a three-minute tutorial that will introduce you to the concepts of data visualization, provide examples of how it is done, and show you some online tools to get you started:
Moreover, there are some basic things that you must consider when you want to create a visual to display a data.
- At first you must to make sure that you have understood deeply the information that has been given to you to visualize.
- Then make clear what kind of data is that you want to communicate.
- You must know who will you audience will be and understand how the specific audience process visual data.
- Last, make sure that you use a simple and understandable form for your audience to realize what this information that is provided from your visual representation.
BAD AND GOOD EXAMPLES OF DATA VISUALISATION
In my opinion a good example of data visualization is the Interactive timeline that was created by The Guardian. As Benjamin Wiederkehr has mentioned in his article this interactive timeline shows the most important incidents and how they spread over the different neighborhoods. The user can scroll through a 3D timeline and watch how the riots unfolded. Every event is marked and linked to the belonging article.
I believe that this is a good example because the information that are presented to the viewer are clear and beautiful net. It is an interesting way to capture the attention of a person.
The only text that appears is just to explain to the user a few important things. Moreover, the user can find easily the information that may interest him and the most important thing is that is not misrepresenting what the data have to say.
On the other hand, a visual representation that was published in the webpage of “The Economist”, in my opinion, failed to deliver the data that it meant to deliver to the audience. By taking a glance at the images below you cannot understand the information that this visual representation wants to deliver. The reason is because there is no title or any key in order to explain to the user its purpose.
