This example illustrates how to use the attributes of the Arc element to control the appearance of a VML shape.
<!-- Include the VML behavior -->
<style>v\: * { behavior:url(#default#VML);display:inline-block }</style>
<!-- Declare the VML namespace -->
<xml:namespace ns="urn:schemas-microsoft-com:vml" prefix="v" />
<v:arc style="width:100pt;height:100pt" startangle="0" endangle="180" strokecolor="red" strokeweight="2pt"/>
