Labella.js
labella.js is a JavaScript data visualization library and label collision avoidance engine. It functions as a one-dimensional layout solver designed to calculate non-overlapping text label positions along a single axis to ensure readability in web-based charts.
The library operates as a timeline labeling utility that prevents visual clutter in custom charting components. It uses a spatial constraint engine to dynamically adjust element coordinates and manage the systematic placement of text markers across temporal data sets.
The project covers data visualization labeling and timeline axis layout, utilizing techniques such as force-directed layout optimization, greedy interval packing, and constraint-based position solving to handle one-dimensional collision detection.
