The way of representation of data in a visualization tool attracts our eye; that is the simple way to engage ourselves to understand the information. Different colors, patterns, and graphs keep us intact to the visualizations. Due to this reason, data visualization is the biggest benefit to many fields. Similar logic is with charts and spreadsheets, making our work much more effective. Today, many professionals are taking data visualization courses to learn more about this field.
