Abstract: Server-side chart layout for web applications is provided. Output of a server-side layout engine is exposed on the web via a server-side web service and a client-side web player that communicates with the web service. The web player is operative to send chart definitions to the web service, and receive a scene graph of a resultant chart layout. The scene graph includes normalized and annotated information to draw the chart, animate transitions, implement interactivities, and provide standardized accessibility locally within a web client. Aspects enable chart fidelity across native and browser endpoints, and provide faster chart load and render performance that is unaffected by growth of data size or expansions in provided chart features.

Abstract: Morphing animations between arbitrary chart states in a web client application are provided. A morphing animation engine interpolates changes between a first output state (before geometry) and a second output state (after geometry), aligning the before and after geometries by semantic identifiers encoded in the geometry. The morphing animation engine further performs simple geometric transitions of geometric primitives for producing an unlimited number of intermediate states (key frames) between any two arbitrary chart states without requiring per frame layouts. According to an aspect, processing times for producing intermediate frames are minimized, allowing for animations to have consistent rendering and achieving a high frame rate (60 FPS).

Abstract: Generating a chart-type agnostic data structure for defining a chart for use in chart rendering, animation, interactivity, and accessibility via a web client is provided. Aspects of a charting system are operative to represent output of a server-side chart layout engine in a data structure that can transmitted to and consumed by the web client for rendering an interactive chart. For example, aspects of the charting system enable for chart layout and chart rendering to exist separately, providing efficient chart layout and preventing external exposure of chart layout code.

Abstract: Technologies are described herein for authoring, sharing, and consuming online courses. A lesson creation extension executing in conjunction with a presentation application can be utilized to create an augmented presentation document having one or more slides. A video recording of a presentation of the slides may be made and associated with the slides. Digital ink made on the slides may also be recorded. The slides might also be created to include quizzes, interactive labs, and other types of interactive content. The augmented presentation document can then be published to a portal system for sharing. A lesson player can be utilized to play back the lesson from the portal system. During playback, the recorded audio, video and digital ink are played back in synchronization by the lesson player.
