Charts backed by Google Sheets auto-refresh every 15 minutes in LiquiChart's living content infrastructure

In LiquiChart's living content infrastructure, a chart backed by Google Sheets auto-refreshes every 15 minutes. When the spreadsheet changes, every embed updates automatically. No re-exporting, no re-uploading. A [trend poll](/blog/trend-polls-vs-static-polls) stays open, rolls over monthly or quarterly, and accumulates responses that reveal direction over time. The same chart that showed March data in March shows April data in April, with the full history preserved.
