Data Analysis Chat Block for Ark UI

Everything. The three series are typed arrays, the analyst's answers come from a short script keyed on the quoted point, and no query runs. To wire it for real, load the series for the chosen range where RANGES is read, send your reply with its quoted point id where post runs, and append the analyst's messages to the same list.

Yes, in two places. Every bar is a button whose name holds its figures ("Tue 6 Oct, 412 orders. Press to reply to this point."), so a screen reader walks the chart as a list of named buttons, and the caption states the peak and the total in words. Colour never carries the highlight: a pressed bar is solid foreground and announced as pressed.

A bar press stores the point, shows the chip and moves focus to the composer; pressing the same bar again, using the chip's close button or changing the range removes it. Sending posts your text with the quote inside the bubble and spends the chip, so one reply quotes one point.

Enter sends and Shift and Enter add a line, which the field's description says for a screen reader; Enter during text composition (an IME) is left alone. Send stays quiet while the field is empty and says so if pressed, and focus stays in the field after sending.

The log is a focusable region announced as a log. The range switch and every bar are keyboard controls with visible focus, the status line says what is quoted or removed, and the quote chip is a plain line with a named close button.

The same single column: the chart card narrows to the log's width and its bars keep a tap target the full height of the plot, the quote chip truncates, and the window keeps its height with only the log scrolling.
