Data visualization is the process of assisting people to comprehend the meaning of data presented to them by portraying it in the form of visuals. Data visualization is of great importance since it is easier for the human brain to perceive facts represented in form charts and graphs than a large amount of information in the form of reports. At the beginning of the video, DavidMcCandless pointed out that people are faced with the challenge of information overload, and suggested that the only solution is to maximize the use of our eyes to visualize information more. Visualization assists to establish patterns and connections, and, thus, we can come up with information that makes sense.

Patterns ensure that we can focus on what matters mostout of a large pool of information. Thereby, time that would have been used in going through lots of information gets reduced. McCandless alluded to the fact that we tend to create an information map that is useful whenlost in informationby visualizing data. One example pointed out by McCandless was the fact that the United States has the most significant military budget in the world. Many will view this as America trying to have control of the rest of the world, but the truth is that America is a rich country, and, thus, its military budget is likely to be huge. This is possible due to the fact America`s economy can afford to have such a large budget. When we bring in another data set such as budget proportion to GDP, then America does not come in first place. In conclusion, visualization can offer quick solutions to information problems in the society.
