    <Expander>
        <TeachingTip IsOpen="True" Title="City Village" Subtitle="Chart Legend highlighted in HeroContent">
            <TeachingTip.Content>
                <Image Source="ms-appx:///Assets/Qantas.svg" Margin="5"/>
            </TeachingTip.Content>
            <TeachingTip.HeroContent>
                <GridView ItemsSource="{x:Bind ViewModel.Items}">
                    <GridView.ItemsPanel>
                        <ItemsPanelTemplate>
                            <ItemsWrapGrid MaximumRowsOrColumns="3" Orientation="Horizontal"/>
                        </ItemsPanelTemplate>
                    </GridView.ItemsPanel>
                    <GridView.ItemTemplate>
