%description
A 'Shiny'-based interactive platform for end-to-end data science
workflows. Provides modules for data import (CSV, 'Excel', RDS, TXT), data
preprocessing (missing value imputation, encoding, scaling, outlier
removal), exploratory data analysis with interactive plots and normality
tests, supervised learning (regression and classification each with eight
algorithms), and unsupervised learning (k-means, hierarchical clustering,
density-based spatial clustering of applications with noise). Designed for
students and practitioners in data science and artificial intelligence.
