Reading Between the Lines: Toward Human-Centered Clutter Reduction in Line Charts
Abstract: Line charts are among the most widely used tools for communicating time-series data, yet as datasets grow larger and noisier, they quickly become cluttered. While many strategies exist to reduce this clutter, their effects on what viewers actually perceive remain poorly understood. This dissertation argues that effective clutter reduction requires bridging the technical space of visualization techniques with the human space of perception.Four studies build this connection. The first evaluates layout-based and aggregation-based strategies, showing that aggregation better preserves trends and supports more reliable interpretation. The second introduces visual stenography to examine what viewers retain in noisy charts, revealing that perception is highly individualized and driven by feature prioritization. The third formalizes the technical design space through a feature-based taxonomy of 19 simplification algorithms…

Topology-Aware Hashing and Sketching for Scalable Scientific Visualization and Uncertainty Analysis, Abstract: Modern scientific simulations and observational pipelines generate massive, high-dimensional data, posing significant challenges for scalable analysis, comparison, and interpretation. This thesis introduces two topology-aware data summarization strategies, hashing and sketching, to support scalable scientific visualization while preserving essential structural features and enabling principled uncertainty quantification.
We first develop an efficient framework for the comparative analysis of scalar fields using locality-sensitive hashing (LSH) on merge trees, enabling scalable similarity queries over large ensembles. To further support scalable modeling, we propose coreset-based sketching methods for kernel regression and kernel density estimation, producing compact surrogate representations that preserve topological structures such as Morse complexes and associated density ridges with high fidelity.…
