Wt

(Not a bug in wt itself but in the Widget Gallery.)

There are pages in the widget gallery that contain wrong links into the Wt reference:

https://www.webtoolkit.eu/widgets/graphics-charts/category-chart
https://www.webtoolkit.eu/widgets/graphics-charts/pie-chart
https://www.webtoolkit.eu/widgets/graphics-charts/3d-category-chart

It seems that most links into the chart namespace are wrong due to a missing namespace.
E.g. "CartesianChart" at the very top of https://www.webtoolkit.eu/widgets/graphics-charts/category-chart links to
https://www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1WCartesianChart.html
instead of
https://www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1Chart_1_1WCartesianChart.html

The links on the other pages in the "Graphics and Charts" chapter are correct,
e.g. in https://www.webtoolkit.eu/widgets/graphics-charts/3d-numerical-chart

The working links have the namespace "Chart" in the link text. This is missing on the pages with wrong link targets.
