Multi-Source Data Extraction & Visualization
3-Day Intensive Course for Analysts, Engineers & Technical Managers
3 Intense Days
7 Hours per Day (Split into two 3.5-hour sessions)
Learning Path Visual
From raw data to clean insights across systems and formats:
Day 1: Data Extraction from IoT Devices & APIs
Understand the landscape of connected devices and streaming data. Learn to extract sensor and telemetry data from IoT platforms using Python, REST APIs, and CSV/JSON integrations.
Day 2: Data Cleaning & Structuring with NumPy & Pandas
Use Python’s core data tools to organize and clean data. Learn best practices for working with arrays, time-series, missing values, multi-source merges, and relational joins.
Day 3: Visualizing Data with Matplotlib & Insights Communication
Transform complex datasets into clear visual stories. Learn to use Matplotlib for custom graphs, dashboards, and real-time monitoring. Communicate findings for reports, teams, or strategic decisions.
Course Overview
This course teaches you how to extract, clean, and visualize data from multiple real-world sources — including IoT systems, CSV/JSON files, and live APIs — using industry-standard Python tools. Whether you’re managing devices, running experiments, or analyzing supply chain data, you’ll learn how to go from raw data to structured insights in three intensive days.
Perfect for those who want to go beyond Excel, and turn sensor streams, logs, and web services into actionable visual intelligence.
You’ll learn how to:
-
Connect to and extract data from IoT endpoints, web APIs, and raw files
-
Structure and clean datasets using NumPy arrays and Pandas DataFrames
-
Merge and process multiple data sources into usable formats
-
Visualize trends, distributions, and anomalies with Matplotlib
-
Handle time-series and real-time data challenges
-
Communicate technical results clearly to decision-makers
