Data Visualization

The Art of Data Visualization

• Every single pixel should testify directly to the content.
• Data is just a clue to the end truth.
• We're dealing with data systems that are larger than anything.

One lesson I've learned from watching the video is that data visualization is another form of visual art that grabs our interest and keeps our eyes on the message. When we see a chart, we quickly see trends and outliers. If we can see something, we internalize it quickly. Data visualization is data representation using common graphics, such as charts, plots, infographics, and even animations. These visual displays of information communicate complex data relationships and data-driven insights in a way that is easy to understand. The main goal of data visualization is to make it easier to identify patterns, trends, and outliers in large data sets. Comparing objects by aligning them with the same parameters is the most popular visualization out there. Bar charts can be used to track changes over time. However, bar graphs used for time series yield accurate results when the changes are considerably large.
