SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pandas, numpy, scikit-learn, plotly, dash, dash-bootstrap-components, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Manually cleaning messy CSV data with missing values, performing statistical analysis, and building interactive visualizations is time-consuming and prone to human error, especially for large or complex datasets.

Core Features & Use Cases

  • Intelligent Missing Value Handling: Automatically detects missing data patterns, recommends optimal imputation strategies (mean, median, KNN, etc.), and cleans datasets without manual intervention.
  • Interactive Dashboard Generation: Builds Plotly Dash dashboards with summary statistics, time series trends, distribution plots, correlation heatmaps, and categorical analysis for exploratory data analysis.
  • Use Case: A business analyst with a quarterly sales dataset full of missing customer demographic entries can use this skill to automatically impute missing values and generate an interactive dashboard to explore sales trends across regions.

Quick Start

Use the data-analyst skill to clean the missing values in your customer_survey.csv file and generate an interactive dashboard to visualize response trends across demographic groups.
