dsh-oil-account

Most oil-vs-EV comparisons live and die in static spreadsheets. dsh-oil-account turns the exercise into a repeatable eight-second animated demo: switch the time horizon, slide the annual mileage, and an SVG cumulative-cost curve redraws while a cartoon presenter talks, with mouth movement and a waveform pulsing in sync. The whole sequence is built for screen recording—one click replays the entire take.

All calculations run locally as pure functions covering purchase price, energy, maintenance, and insurance. You can toggle between 3, 5, 8, and 10 years and dial annual mileage anywhere from 5,000 to 50,000 km; the default eight-year figure lands at 43,600 yuan. When the browser supports speechSynthesis, a Chinese narration plays automatically; otherwise the visual demo still completes without a hitch. No paid model is called and no user data leaves the machine.

The plugin is aimed at developers preparing Better Sidebar recordings, product demos, or tech talks, and at UI enthusiasts who enjoy parameter-driven animation. A word of caution: the pre-set figures exist for playful product demonstration only and should not be read as real vehicle pricing or purchase advice.
