ATTRIBUTION REQUIREMENT

Any product, website, or application that displays charts rendered by this
software must show a visible attribution to the Vela project on every page or
screen where such a chart is displayed.

The library satisfies this requirement automatically: it renders an attribution
mark (the project logomark linking to the Vela project page) on the chart
itself, enabled by default. You may restyle or reposition this mark to fit your
design.

You may disable the built-in mark (renderer feature `attribution`) ONLY if you
display an equivalent visible attribution — the name "Vela" together with a
link to the project page above — elsewhere on the same page or screen, in a
place available to your users.

Removing, hiding, or obscuring the attribution without providing the
equivalent notice described above is not permitted.

This file constitutes the NOTICE file described in Section 4(d) of the Apache
License, Version 2.0: redistributions of this software, in source or binary
form, must include a readable copy of these attribution notices.
