 The [text mark](./README.md#text) now supports automatic wrapping! The new **lineWidth** option specifies the desired length of a line in ems. The line breaking, wrapping, and text metrics implementations are all rudimentary, but they should be acceptable for text that is mostly ASCII. (For more control, you can hard-wrap text manually.) The **monospace** option now provides convenient defaults for monospaced text.
 
-Plot now supports ARIA attributes for improved accessibility: aria-label, aria-description, aria-hidden. The top-level **ariaLabel** and **ariaDescription** options apply to the root SVG element. The new *scale*.**ariaLabel** and *scale*.**ariaDescription** options apply to axes; the label defaults to *e.g.* “y-axis” and the description defaults to the *scale*.**label** (*e.g.*, “↑ temperature”). Marks define a group-level aria-label (*e.g.*, “dot”). There is also an optional **ariaLabel** channel for labeling data (*e.g.*, “E 12.7%”), and a group-level **ariaDescription** option for a human-readable description. The **ariaHidden** mark option allows the hiding of decorative elements from the accessibility tree.

 The line and link marks now support [marker options](./README.md#markers) for drawing a graphical marker (such as a dot or arrowhead) on each vertex. Circle and arrow markers are provided, or you can implement a custom marker function that returns an SVG marker element. Markers automatically inherit the stroke color of the associated mark.
