DeepSeek V4.1 Flash in a raw API call

Create a single self-contained HTML file (inline CSS and JavaScript only; SVG for all graphics; no canvas, no external libraries, fonts or network requests) that plays a polished motion graphic, like a studio-made data animation.

The motion: one dataset of 6 values (Mon-Sat: 42, 68, 55, 90, 74, 61) morphs through three chart states in a continuous loop:
1. Bar chart: 6 bars grow up from the baseline, with axis, gridlines and value labels.
2. The bars smoothly morph into a line chart: each bar collapses into a point at its top, the points connect with a line that draws itself, and an area fill fades in beneath it.
3. The line chart morphs into a donut chart: the 6 values become 6 coloured arcs that sweep around a ring, with the total counting up in the centre.
4. The donut morphs back into the bar chart and the loop repeats.
Each state holds for about 2 seconds and each transition takes about 1.5 seconds, so one loop is about 14 seconds. Every element must visibly travel from one state to the next (true morphing, not a crossfade). Each state shows a small label naming it ("Bars", "Line", "Donut"), and labels animate in and out.

Requirements:
- Use expressive easing (ease-in-out, overshoot, staggered delays between the 6 elements).
- Dark, modern design with a cohesive colour palette; portrait 4:5 layout, scaled to fit the browser window and centred.
- Motion starts immediately at page load: something is already moving in the first half second.
- Drive all animation with requestAnimationFrame and performance.now; no user interaction needed.
- No other text, titles, buttons or UI beyond the chart labels, values and state labels.
