Source: https://github.com/tradingview/lightweight-charts — clone it and read its README and examples before writing anything; its documented setup beats what you remember. Stack: a TypeScript charting library — create a chart, add a series, and call setData(); a standalone IIFE build is also available via CDN with no bundler. Needs: Node/npm for the package install, or nothing beyond a script tag for the CDN build. Start: `npm install lightweight-charts`, then createChart() + chart.addSeries(CandlestickSeries) + setData() with a handful of bars from the README example. Limit: the licence requires an attribution notice and a link to tradingview.com on any page that uses it — the built-in attributionLogo chart option satisfies this by default. Done means: you show me a rendered chart in my browser with my own data, and the code you wrote. Before you start, ask me: where my OHLC data is coming from, and, if there is no project in this folder yet, whether I want a plain page or a framework.
