SightLine: Building on the Web's Visualization Ecosystem.

The advancement of tools for web designers and developers have transformed the internet into a vibrant ecosystem for data visualization and analysis. However, even when there are hundreds of visualizations exploring the same topic, they are often viewed in isolation with no mechanism to navigate between them. We built SightLine - a web portal that passively collects and organizes visualizations - to explore the design space of the web's scattered visualization ecosystem. By preserving the context of each visualization visit, we enable personal provenance through a \"visualization history, discovery and exploration through trending visualizations, and targeted search by querying SightLine's extensive metadata collected for each visualization.
