Supervised and Unsupervised Learning are two primary types of machine learning, differing mainly in hThe primary goal of a data science project is to extract actionable insights from data to support better decision-making, predictions, or automation—ultimately solving a specific business or real-world problem.

Data visualization is important in analytics because it transforms complex datasets into clear, visual representations—such as charts, graphs, and dashboards—that make patterns, trends, and insights easier to understand.

Key reasons it’s important:

  1. Simplifies complexity – Large datasets can be overwhelming in raw form; visuals make them digestible.

  2. Reveals patterns & trends – Helps identify correlations, outliers, and changes over time.

  3. Enhances decision-making – Clear visuals help stakeholders quickly grasp the situation and act on insights.

  4. Improves communication – Makes data more accessible to non-technical audiences.

  5. Supports storytelling – Combines data with narrative to explain why something is happening.

Example:
Instead of showing a table with thousands of sales numbers, a line chart can instantly highlight seasonal peaks, downward trends, or unusual spikes.

In short, data visualization turns raw numbers into a visual story, making it faster and easier for people to make informed, data-driven decisions.
