Each bar consists of a vertical - line showing the high-low range, with a left tick for the opening price and a - right tick for the closing price. Green bars indicate "up" days (close > open) - and red bars indicate "down" days (close < open). The chart shows a general downward - trend from around $165 at the peak in mid-June to approximately $125-130 by early - August. The title "ohlc-bar · plotnine · pyplots.ai" is displayed prominently - at the top in bold. The Y-axis shows "Price (USD)" and the X-axis shows "Date" - with labels at Jun 03, Jun 17, Jul 01, Jul 15, and Jul 29. A legend on the right - explains the color coding for Direction (Down/Up).
