The concept behind this finance data video

Multi-chart data film for an investor update or quarterly review — Strata turns several D3 charts into one narrated briefing. Bars, lines and distributions carry the read, each chart entering on the beat of the voice-over. It is the format for the quarterly review, the investor update, the market read that has to feel authoritative without a slide in sight.

The craft is in the choreography: charts that build in sequence, axes that resolve cleanly, a narration that lands each figure as the visual completes it. Every number is sourced and on-screen-honest, built from the dataset exactly as provided — clean enough to put in front of a brand or legal review, with figures you supply and approve. A self-initiated concept piece — studio spec work, illustrative facts only.

A narrated report film where every bar carries its figure and its share

The brief this format answers is always some version of "make the numbers land without lying about them". So the main plate ranks the world’s electricity sources in a single horizontal read, and every bar carries both its absolute figure in terawatt-hours and its share of the total. A bar you cannot read a number off is decoration, and a share without an absolute hides the size of what is being shared — the two most common ways a chart flatters the person who commissioned it.

Two callout pills sit on the plate carrying the actual reading of the chart: that fossil generation is still the base, and that solar and wind are the ones moving. A data film that only shows and never states leaves the viewer to guess what they were meant to see, and viewers guess generously. Along the bottom a second layer runs country figures as a tape, the way a desk actually reads — the headline plate for the structure, the ticker for the texture underneath it. The dataset is credited on the plate under its open licence, which is a condition of using it and also the point.

One more thing is burned into this film rather than written on this page: the word CONCEPT, set into the running head and repeated beside the year range. The honesty label on this site is only worth something if it survives the clip leaving the site, so on the pieces where it matters most it lives in the pixels. Screenshot the frame, re-post it anywhere, and it is still labelled.

Read the narration in full — 11 passages, verbatim

Taken from the caption track this player loads — not a summary of it, so anything the film claims can be checked against the frame that carries it.

Here's the tape. Read it fast. Solar and wind.
Thirty-two terawatt-hours in two thousand. Forty-six fifty-two now. A hundred forty-five times.
It left the floor in twenty-ten. Then, vertical. But the old book's still open.
Coal, thirty-four percent. Gas, twenty-two. Fossil's still the majority.
Growth's at the margin. The mass hasn't moved. Look who's biggest.
China. America. Most power, mid-table on clean.
France, up here. Ninety-five percent clean. Small book, cleanest desk.
Different book on every desk. Asia, half coal. South America, half hydro.
Europe, balanced. Momentum versus mass. The transition's real.
The base is enormous. Both true. Strata.
We turn your real numbers into films like this. Every figure cited.
