Accessibility commitment

CensusIO targets WCAG 2.2 Level AA. This page is an honest account of what that means in the product today: what is built, and what is still ahead.

What is built

Semantic HTML and native controls. Buttons, links, selects, and checkboxes are the real elements, so keyboard and assistive-technology behavior comes from the browser rather than from custom code that has to reimplement it.
Keyboard operation. Navigation, forms, and dialogs work from the keyboard, and dialogs close with Escape. Focus order follows the order of the page.
A skip-to-content link. Hidden until you tab to it, then it appears so keyboard users can jump past the navigation straight to the main content.
Visible focus. A clear outline marks the element you are on, so you never lose your place while tabbing.
Reduced motion. If your system asks for reduced motion, CensusIO honors it and collapses animations.
Screen-reader labels. Form fields carry labels, dialogs carry accessible names, and icon-only buttons carry text for screen readers.
Text alternatives for charts and maps. The distribution charts (histogram and scatter) offer a “Show data table” view of the numbers behind the bars and points, and the records map offers a keyboard-reachable list of its records that locates each one on the map. The information in a canvas visual is available without a mouse.
Keyboard menus. The header menus follow the standard menu pattern: arrow keys move between items, Home and End jump to the ends, typing a letter jumps to a match, and Escape closes and returns focus to the button that opened the menu.
An automated check on every change. An accessibility linter (eslint-plugin-jsx-a11y) runs in our continuous integration, so a change that drops a label or breaks ARIA is caught before it ships.
A declared page language. Every page declares its language, so a screen reader pronounces it correctly.

What is still pending

We would rather tell you the gaps than imply there are none.

A formal audit with assistive technologies (NVDA, JAWS, VoiceOver) has not yet been completed.
A measured color-contrast pass is planned. The palette was chosen with contrast in mind but has not been formally measured.
A full landmark and heading-order review, and a complete pass over informative images, are in progress.

If you use CensusIO with assistive technology and hit a barrier, tell us. A real report from a real workflow is the most useful thing we can get, and it goes to the front of the line.
