Oracle Accessibility Conformance Report

VPAT® Version 2.3 - April 2019

Name of Product:

Graph Visualization Toolkit 24.1.0

Product Description:

Graph Visualization Toolkit is a graph visualization component that can be embedded into web applications to visualize graph data.

Data can be supplied to the component through the exposed handles via web platforms in which it is consumed, and the component renders graph using the data. It also adds an interactive visual layer that supports filtering graphs, highlighting elements, visualizing geographical data, and expanding/contracting the view, enabling users to explore large graphs intuitively.

Notes:

none

Graph Visualization Toolkit supports keyboard-only support for all major graph operations and navigations that can otherwise be performed using a mouse. The main key combinations are:

Tab: Move focus to next element.

Shift + Tab : Move focus to previous element.

Arrow Keys : When focus is on a node/edge, moves focus and selection to the adjacent node/edge in hierarchy based on order of ID value of the node/edge. Up/Right arrow moves to the node/edge with the next higher ID value, Down/Left arrow key moves to the node/edge with the next lower ID value.

Alt + Arrow Keys : Switch from Vertex to edge and vice versa

Ctrl + Alt + Arrow Keys : Pan in the direction of the arrow.

Alt + Spacebar / Menu key : Opens tooltip

Esc key : Exit tooltip

+ Key : Zoom in one level.

- Key: Zoom out one level.

Evaluation Methods Used:

Oracle's policy is to design, develop and test both products and documentation to be accessible. The recommended styles of testing for accessibility include: (i) algorithmic automated tests, (ii) human judgement tests such as tool-assisted tests, visual inspection and manual operation, and (iii) testing with assistive technology by people with and without disabilities. Additional information about Oracle's accessibility program is available on http://www.oracle.com/corporate/accessibility/index.html
