Description

The animation displays a table of eight steps showing median positions, heights, a constant width, and the computed area for each slice of a shape. The column headers are rendered as plain text labels (e.g., "STEP", "med pon", "height (cm)", "math (cm)", "area (cm²)") rather than mathematical expressions. The table appears near the top of the frame, scaled to half size, with white grid lines on a dark background. Directly below the table, right‑aligned, the summed‑area expression $\sum A = 85.6\ \text{cm}^2$ fades in. A brief pause allows the viewer to absorb the information.

Phases

#	Phase Name	Duration	Description
1	Table Appearance	~2.5s	The table fades in while its outer border and grid lines are drawn; cells become visible simultaneously.
2	Total Area Reveal	~0.5s	The summed‑area label $\sum A = 85.6\ \text{cm}^2$ writes itself just below the table, aligned to the right edge.
3	Hold	~3.0s	A pause for readability.

Area Descriptions

Area	Content	Notes
Main	A MathTable with 8 rows and 5 columns. Column headers are plain Text objects: "STEP", "med pon", "height (cm)", "math (cm)", "area (cm²)". Each row contains the step data and the area formula (e.g., 4 \times 1 = 4 \text{ cm}^2). The table is scaled to 0.5 and positioned near the top edge with a small buffer.	Occupies the upper portion of the frame, centered horizontally and shifted slightly upward.
Caption	The summed‑area expression $\sum A = 85.6\ \text{cm}^2$.	Placed directly below the table, right‑aligned with the table’s right edge.

Notes

• Assumptions: No additional titles or explanatory text are required beyond the table and summed‑area label. The animation remains a single‑Scene implementation.
• The column headers are rendered as Text (plain font) rather than MathTex, matching the provided code.
• All grid lines and text are white for high contrast against a dark background.
• Timing mirrors the original specification, with a short 0.5 s interval before the sum label appears (as in the code).
