- Gantt Charts - Displays project tasks as horizontal bars on a calendar timeline with drag-and-drop rescheduling and dependency arrows.
- Project Timelines - Displays tasks as horizontal bars on a calendar to visualize project schedules and durations.
- Temporal View Switching - Switches the chart's time scale between day, week, month, or year to match project granularity.
- Gantt View Customizers - Switches the chart's time scale between day, week, month, or year and configures visual appearance like bar dimensions and grid lines.
- Gantt Charts - A JavaScript library for rendering interactive project timelines with draggable task bars and dependency arrows.
- Timeline Layouts - Provides the core layout engine that positions all task bars on the Gantt timeline.
- Chart Configuration Updates - Updates chart options and re-renders the timeline without reloading the page, including modifying individual tasks in place.
- Task Dependency Management - Links tasks with predecessor-successor relationships and updates the timeline automatically when dependencies change.
- Gantt Progress Indicators - Fills each task bar with a percentage-complete indicator to communicate how much work is done.
- Gantt Progress Trackers - Shows the percentage of completion for each task as a filled portion of its bar, and allows users to edit it.
- Gantt Progress Editors - Shows task completion percentages as filled bar portions and allows users to edit progress interactively.
- SVG Chart Renderers - Renders the entire Gantt chart as a single SVG element for crisp scaling and direct DOM manipulation.
- Predecessor-Successor Graphs - Models task dependencies as a directed graph to automatically update dates when links change.
- Gantt Scheduling UIs - A user interface for visualizing and editing project schedules with support for dependencies and progress tracking.
- Task Dependency Visualizers - Draws arrows between linked tasks to show which tasks must finish before others can begin.
- Gantt Dependency Visualizers - Links tasks with predecessor-successor relationships so the chart updates when a dependency changes.
- Time Scale Switchers - Switches the timeline scale between day, week, month, or year for different granularity views.
- Event Rescheduling - Lets users drag task bars to new dates, updating the timeline interactively.
- Gantt - A web component that displays tasks as horizontal bars on a calendar with drag-to-reschedule functionality.

- Immutable Configuration Setters - Accepts all chart options as a single immutable configuration object that triggers re-render on reference change.
- Time-Range Viewport Clippers - Optimizes rendering by clipping the SVG viewBox to the visible time range.
- Bar Edge Draggers - Adjusts start dates or durations by dragging bar edges directly on the timeline.
- Task Progress Bars - Renders a progress indicator on each task bar to show completion percentage.
- Timeline Navigators - Scrolls the view to the current date, start, or end of the project with a jump-to-today button.
- Data Attribute Event Mapping - Implements event delegation by mapping data attributes on SVG elements to interaction handlers.
- Data Visualization - Interactive modern Gantt chart library.
- Game Engines - Interactive Gantt chart library for the web.
