IDMD - Interactive Data Manipulator and Descriptor

Interactive Data Manipulator and Descriptor (IDMD)

Overview

The Interactive Data Manipulator and Descriptor (IDMD) is a Python package designed for interactive data exploration, manipulation, visualization, and reporting. It provides a modular structure for handling datasets, making it easy to extend and maintain. (Scientific Python course at PPCU - project work)

Dependencies

The IDMD package requires the following main dependencies:

• matplotlib
• streamlit
• pandas

For specific version requirements, refer to the requirements.txt file. If you are developing or contributing to the project, additional tools for code quality, formatting, linting, and testing are listed in requirements-dev.txt.

Package Structure

data Module

Handles all data-related operations, such as file uploading, dataset generation, and exporting.

• Submodules:
  • export.py: Handles exporting datasets to CSV or other formats.
  • generator.py: Generates sample datasets with different distributions.
  • uploader.py: Handles file uploads and loading datasets.

---

manipulation Module

Provides functionality for manipulating datasets.

• Submodules:
  • columns.py: Handles column-specific operations like swapping, dropping, and selecting columns.
  • replace.py: Handles value-specific operations like replacing values with mean, median, or other methods.

---

ui Module

Contains components for rendering the Streamlit interface.

• Submodules:
  • base.py: Defines the abstract Component class for all UI components.
  • columns_ui.py: Provides UI for column manipulation.
  • data_preview.py: Displays a preview of the dataset.
  • data_stats.py: Displays dataset statistics and metadata.
  • exporter_ui.py: Provides UI for exporting data.
  • generator_ui.py: Provides UI for generating data.
  • replace_ui.py: Provides UI for replacing operations.
  • uploader_ui.py: Provides UI for file uploading.
  • visualizer_ui.py: Provides UI for visualizing data, including default and custom plots.

---

visualization Module

Handles data visualization.

• Submodules:
  • plots.py: Generates various types of plots (e.g., line plots, bar plots).
  • heatmaps.py: Generates correlation heatmaps.
  • histograms.py: Generates histograms.
  • visualizer.py: Utility class for generating visualizations, including line plots, histograms, and heatmaps.

---

report Module

Handles report generation.

• Submodules:
  • report.py: Generates PDF reports with data and visualizations.

---

app.py

Orchestrates the integration of all components and runs the Streamlit application.

Features

1. Sample Dataset Generation:

   • Generate datasets with different distributions (e.g., normal, uniform).
   • Easily create synthetic data for testing and exploration.

2. Data Manipulation:

   • Swap, drop, and select columns.
   • Replace missing values with mean, median, or other methods.
   • Normalize or remove outliers.

3. Data Visualization:

   • Generate interactive plots, histograms, and heatmaps.
   • Explore data visually with Streamlit's interactivity.

4. Data Export:

   • Export processed datasets to CSV format.

5. Report Generation:

   • Generate PDF reports with data summaries and visualizations.

Example Usage

Run the example application using:

streamlit run example_app.py

You can also explore the interactive example notebook example_app.ipynb that demonstrates:

• Package installation
• Creating a complete dashboard application
• Running the app locally or on Google Colab
• Using all major components of the package

Opening the resulting website, should show a dashboard like this:

Loading or generating data should show a similar result:
