Data Visualization – Importance and Tools (Tableau, Power BI)
Data is everywhere around us – in business, social media, shopping, and even in daily life. But raw data is often confusing and hard to understand. Data Visualization helps us by turning data into pictures like charts, graphs, and dashboards.
Why Data Visualization is Important
* Easy to understand – Turns big data into simple visuals.
* Shows patterns and trends – Helps us see growth, decline, or sudden changes.
* Supports quick decisions – Managers and teams can act faster with clear insights.
