Common mistakes Data Visualization

The idea in one minute

Data Visualization is the ability to apply domain knowledge, judgment, and repeatable methods to produce a professional outcome rather than simply recognize terminology. In practice it combines correctness, system behavior, reliability, maintainability, security, and engineering trade-offs. Competence means diagnosing the situation, choosing an approach that fits the constraints, executing it, checking the result, and adapting when evidence shows the approach is not working. Strong practitioners can explain both what they did and why the method was appropriate.

This capability connects directly with SQL, Project Management, Statistical Analysis. Open those concepts when the lesson depends on them rather than treating Data Visualization as an isolated ability.
