The template (templates/charts/pie_chart.svg) is correct — your agent (OpenCode + GLM-5.1) just isn't following it when drawing the arcs.

Fix: point the agent at templates/charts/pie_chart.svg and ask it to re-render the failing slides using the same arc-flag and endpoint conventions shown there. It should self-correct.
