A simulated Power BI custom visual in chart mode. Tab to the chart and use the arrow keys: Left and Right move between quarters, Up and Down between regions and then the quarter's total. Toggle B for Braille, T for Text, S for Sonification, and R for Review mode.
update(). This page writes one by hand, in
the same shape: a categorical data view with a Quarter category and Sales
values grouped by a Region legend field, the way Power BI hands over a
clustered column chart. The page then draws its own SVG and calls
maidrPowerBI.bindPowerBI(element, { chartType: 'column', chart: svg, onNavigate }),
as a visual would in its constructor. Build the bundles first with
npm run build.
In Power BI, the onNavigate callback builds selection ids
from these data points and calls selectionManager.select(),
so the other visuals on the page cross-highlight. Here it only outlines
the bars and writes down what it would select.
