Everything runs in your browser. Nothing you build is sent anywhere.
A statement worth reading is one that says where the product falls short, so this one starts there.
A canvas has no structure for a screen reader to walk. The monitor tab carries the same data as a real sortable table, and the country panels are ordinary markup, so nothing on the map is only on the map. That is a mitigation rather than a fix.
Every ramp is also a legend with numbers, and every country is readable as a row in the monitor, but the map itself does lean on colour. The ranked reading exists partly for this reason: it compresses an extreme spread into a scale that survives most kinds of colour vision.
The causes and chain views pack a lot into a small area. They are keyboard reachable and they read in order, but they are not restful.
Everything that moves respects the reduced motion setting in your operating system. With it on, the reveals, the transitions and the map animations all stand down and the content simply appears.
Light and dark are two designs rather than one inverted. Contrast was checked in both, and the choice is remembered in your own browser.
Every control is reachable, the palette reaches everything else, and focus is visible rather than suppressed.
Switches carry a role and a state, selects carry a label, and the icon buttons carry names rather than symbols alone.
First thing in the tab order on every page.
The layout is built in relative units and survives being zoomed to twice the size without anything being cut off.
A choropleth cannot be read by a screen reader, and pretending otherwise helps nobody. Everything the map shows is also in the monitor as a sortable table with the same figures, and every country has a profile page with its readings in text. The table is not a fallback, it is the same data by another route.
It has to: that is what a layer is. So no reading is ever colour alone. The inspector names the figure, the legend gives the scale in numbers, hovering prints the value, and the monitor has the whole column. A person who cannot separate two shades can still get every number.
Panes arrive, rules draw, figures count up, the page dims as you leave it. All of it stands down completely under the reduced motion setting, including the count on the figures, which then simply show their final value.
Forty eight columns, thirteen hundred commands, forty four levers. The answer is not to remove them but to make them reachable: the command palette finds anything by name from the keyboard, the column chooser hides what you are not reading, and both side panels close.
A canvas element has no internal structure for assistive software to walk. Every chart on a pane is accompanied by the figures it draws, either in the key and value list beside it or in the table beneath it, so the reading never depends on seeing the line.
This has not been through a formal audit. What is written here is what has been built and tested deliberately, not a conformance statement, and anywhere it falls short is a defect rather than a limitation.
