This example presents an interactive stock chart with candlestick and line plots, accompanied by technical indicators such as moving averages, MACD, RSI, and volume. The chart also supports zooming, panning, and draggable annotations for trendlines and support/resistance levels. It uses the D3 v4 library with techan.js for financial charting, rendering to SVG within a React framework. Data is loaded from a TSV file containing historical stock prices and parsed using `d3.timeParse`.
