This document discusses how visualizations like graphs and charts can be used to persuade and potentially mislead people. It notes that studies have shown information accompanied by graphs are seen as more convincing, even if the visualizations don't accurately represent the underlying data. The document then provides several examples of how political campaigns have used charts and maps in ways that spin or omit details from the data for strategic purposes. Overall, it emphasizes the importance of keeping an open and critical eye when interpreting visualizations to avoid being misled.

Editor's Notes
- It’s one of the reasons why data visualization is emerging as a powerful information force in the crowded, intensely contested world of social media. It’s why, during last year’s State of the Union, the president live-tweeted charts to illustrate the points he was making in his speech. It’s why Ezra Klein publishes stories that deign to suggest they can explain something as vast as the Roman empire with a few dozen maps. While most people in the U.S. and Europe are familiarized with graphs and charts during their secondary education, it is the rare person who continues to use this skill throughout the rest of their working life. In later life, the vast majority of these people become unaccustomed to the information being conveyed in these charts and merely accept them on faith. Unscrupulous media outlets, propagandists, activist groups and others rely on this fact and create false impressions with them. More sophisticated users understand that this occurs but are still not competent to identify the fallacies.
- Increasingly, battles of the mind are fought with pictures. Whether in the courtroom, in the boardroom or in a legislative setting, visual imagery is often the primary weapon of choice for those looking to influence decision-making and change minds. Take a look at any of your social media feeds and you'll see why. The world-altering increase in the rate of information exchange caused initially by the Internet and now accelerated by social media platforms has elevated the need for visual persuasion skills. I'd define the visual persuasion as using science-based, visually-oriented methods to influence the decision-making of people, governments and businesses. The key part of the definition, I think, is "science based. We can agree with that argument Graphs Have Magical Powers of Persuasion. Every day we are wokring with data and communicate in visal form very often. But honestly do you feel that are more to be confident about product information if it contains “scientific looking” infos, such as graphs?? Let’s look at a study about how we persuaded by looking charts.
- https://sagepus.blogspot.hu/2017/06/science-visual-abstracts.html In 2014 Cornell Food and Brand Lab published their study in the Public Understanding of Science, trivial elements such as graphs can lead consumers to believe products are more effective. 61 individuals to read information about a new medication Only 67.7% of those who saw only the text believed that that it would reduce illness. 96.6% of those who saw the graph believed that the medication would effectively reduce illness.
- Let”s look at a simple example: This is a part of map which shows tha hungarian see the balaton lake. Here teh used icons such as a tree icon represents more than one tree
- All maps are a lie, but they all lie about different parameters. Thus, the things that are chosen to be distorted in a map provides us with clear insight into human behavior. https://www.tableau.com/about/blog/2017/11/data-map-discovery-78603?utm_campaign=Nurture-CHRTMPGR-ALL-ALL-ALL-ALL&utm_medium=Social&utm_source=Facebook&hootPostID=900fb896ad035629f930e6675e602bab https://research.tableau.com/sites/default/files/Battersby_etal_2014.pdf
- The map most commonly used in the world is the Mercator map. This is the map that we see in classrooms all over the world. This is also the map that formulates our basic ideas of what our planet looks like. In fact, even Google Maps uses the Mercator map. Well, hello Web Mercator. It’s nice to meet you! Tableau uses the Web Mercator map projection for mapping; this is the same map projection that you’ll see in pretty much every web mapping service (Google Maps, Yahoo Maps, etc.). While some people have strong negative opinions of this projection due to the distortion in the high latitude regions, for better or worse, it has become the standard for online mapping https://community.tableau.com/people/sarah.battersby.0/blog/2017/05/12/working-with-projected-data-in-tableau-part-i-map-projection-basics Take a good look at the map. Go on… Really look at it. North America seems larger than Africa, Scandinavian countries are larger than India, and Alaska looks bigger than Brazil. Greenland appears to be a large sparse island big enough to rival Africa. http://cartonerd.blogspot.hu/2014/08/web-mercator-and-comparisons.html Look at the usual flat map of the world and it appears that Greenland is nearly as big as Africa. But it’s not even close. Africa is 14 times larger. Flat maps significantly distort the sizes of countries and continents, the result of converting a spherical surface to a handy rectangle. The area of landmasses becomes increasingly exaggerated toward the poles.
