Towards Scalable Visual Data Wrangling via Direct Manipulation
El Kindi Rezig, Mir Mahathir Mohammad, Nicolas Baret +3
Data wrangling, the process of cleaning, transforming, and preparing data for analysis, is a well-known bottleneck in data science workflows. A wide range of data wrangling techniq…
HOLE: Homological Observation of Latent Embeddings for Neural Network Interpretability
Sudhanva Manjunath Athreya, Paul Rosen
Deep learning models have achieved remarkable success across various domains, yet their learned representations and decision-making processes remain largely opaque and hard to inte…
Visual Stenography: Feature Recreation and Preservation in Sketches of Noisy Line Charts
Rifat Ara Proma, Michael Correll, Ghulam Jilani Quadri +1
Line charts surface many features in time series data, from trends to periodicity to peaks and valleys. However, not every potentially important feature in the data may correspond…
Evaluating Line Chart Strategies for Mitigating Density of Temporal Data: The Impact on Trend, Prediction, and Decision-Making
Rifat Ara Proma, Ghulam Jilani Quadri, Paul Rosen
Overplotted line charts can obscure trends in temporal data and hinder prediction. We conduct a user study comparing three alternatives-aggregated, trellis, and spiral line charts…
