Interactivity agents

Slides the audience interacts with. Today that means live polls and quizzes: the room scans a QR code, answers in Google Forms, and the slide updates in real time by reading the responses spreadsheet through the gviz endpoint over JSONP, so it works even from file://, as long as there is internet and the spreadsheet is public.

/mira-survey

Builds a live poll slide: the audience scans a QR code, votes on a Google Form, and the result updates in real time on the slide (a spinning 3D donut by default, or a bar chart). It takes two links, the voting link (forms.gle/..., which becomes the QR generated locally as inline SVG) and the responses spreadsheet link (docs.google.com/spreadsheets/..., from which the slide reads the tally). It reads the gviz endpoint via JSONP every few seconds, so it works even from file:// with no CORS error; it never uses "Publish to web → CSV" (cached for ~5 min). The spreadsheet must be public (anyone with the link → Viewer). If a link is missing, the agent asks before generating. For a QR without voting use /mira-qrcode; for a static data chart use /mira-chart.

/mira-quiz

Builds a live quiz slide: the audience scans a QR code, answers a multiple-choice question in Google Forms, and the slide reads the responses spreadsheet live through gviz + JSONP. The correct answer stays hidden until the presenter clicks Reveal or presses R; only then does the correct card turn soft green, counts and percentages appear with animated bars, and a basic hit ranking can be toggled with K. It takes the voting link, spreadsheet link, question, options and correct answer. For a poll without a correct answer use /mira-survey.
