Subject: [PATCH] The culprit is in renderChart(): it calls chart?.remove()
 which empties the   container div, causing the layout to collapse to zero
 height for a moment.   The browser then scrolls to keep the viewport
 anchored, but since the page   got shorter it jumps to the top. When the new
 SVG is appended, the page is   taller again but the scroll position was
 already reset.

  Fix: give the chart container a min-height matching the chart height (220px)
  so it never collapses.
