The page https://help.libreoffice.org/6.2/en-US/text/schart/01/choose_chart_type.html?&DbPAR=CHART&System=UNIX shows missing icon for Area. Icon is chart2/res/areas_52x60.svg The SVG icon exist and is accessible, but it does not display. It seems the SVG code is broken. Other SVG icons (e.g. Pie) work OK. Browser used is Firefox and Chromium.
The same problem on Chrome Google Chrome is up to date Version 69.0.3497.100 (Official Build) (64-bit) <img src="6.2/media/icon-themes/chart2/res/areas_52x60.svg" alt="Icon" title="Icon" height="52px" width="60px" class="imageicon">
