Area of Science:

Visual Analytics
Data Mining
Information Visualization

Background:

Identifying clusters in datasets is crucial for pattern discovery.
Heterogeneous datasets present challenges due to data variability and require multi-perspective analysis.
Traditional dendrograms can become cluttered and insufficient for complex datasets.

Purpose of the Study:

To introduce MCLEAN, a visual analytics methodology for enhanced cluster detection in heterogeneous datasets.
To provide a scalable environment for representing and exploring clustered heterogeneous data.
To compare the effectiveness of MCLEAN against dendrograms for cluster identification.

Main Methods:

MCLEAN utilizes a graph-based transformation of relational data.
It combines multilevel data representations with community finding algorithms.
The methodology displays heuristic results to guide user exploration and analysis.

Main Results:

Qualitative user studies demonstrated MCLEAN's effectiveness in aiding cluster detection.
MCLEAN provides a more insightful exploration framework compared to standard dendrograms.
The approach supports scalable representation of heterogeneous datasets through spatialization changes.

Conclusions:

MCLEAN offers a significant advancement in visual analytics for heterogeneous data.
The methodology facilitates more intuitive and effective cluster discovery.
An R package implementation of MCLEAN is publicly available for broader use.
