Supervised and Unsupervised Learning are two primary types of machine learning, differing mainly in how they process and learn from data.

Neural networks are a type of machine learning model inspired by the structure and function of the human brain. They are designed to recognize patterns and relationships in data through a process of learning.

Here are some common data visualization tools that data scientists frequently use, grouped into categories:

1. Programming-Based Tools

These allow highly customized, programmatic visualizations:

  • Matplotlib (Python) – Foundational library for static, publication-quality plots.

  • Seaborn (Python) – Built on Matplotlib; great for statistical and aesthetically pleasing charts.

  • Plotly (Python, R, JavaScript) – Interactive, web-ready charts and dashboards.

  • Bokeh (Python) – Interactive visualizations for large datasets.

  • ggplot2 (R) – Grammar of Graphics-based library for elegant statistical plots.

2. BI & Dashboard Tools

These are often used for interactive business insights and reporting:

  • Tableau – Drag-and-drop interface, strong in storytelling and dashboards.

  • Power BI – Microsoft’s BI tool with strong Excel integration.

  • Qlik Sense – Associative data model for dynamic exploration.

  • Looker – Cloud-based tool with strong integration to data warehouses.

3. Specialized & Web-Based Tools

For quick, shareable visualizations and advanced analysis:

  • Google Data Studio – Free and integrates well with Google services.

  • D3.js – JavaScript library for custom, highly interactive web visualizations.

  • Kibana – For visualizing Elasticsearch data (often in log analytics).

  • Apache Superset – Open-source BI tool for dashboards and data exploration.

✅ Quick Tip for Data Scientists:

  • For exploratory data analysis (EDA) → Seaborn, Matplotlib, ggplot2.

  • For interactive dashboards → Tableau, Power BI, Plotly.

  • For custom web visuals → D3.js, Bokeh.
