Data Visualization
Data Visualization is the skill of turning numbers and information into charts, graphs, and other visual displays that help people understand complex data quickly. It's like turning spreadsheets into stories that anyone can understand at a glance. This skill is important because companies collect lots of information and need people who can present it in ways that help managers make better decisions. People who do this work might use tools like Tableau, Power BI, or even simple tools like Excel to create these visual representations. Think of it as translating raw data into pictures that tell meaningful business stories.
