Cryptocurrency average order price versus size
A live-updating scatter plot contrasts the average price and size of cryptocurrency buy orders, with bubble area encoding the total number of orders per instrument. The visualization streams order data through a WebSocket connection to Coinbase Pro, buffers it, and periodically updates a Perspective table that aggregates values by product. Rendering uses d3fc’s `seriesSvgPoint` and `chartCartesian` with logarithmic scales, while `d3.select` transitions and a greedy label layout place instrument names, toggled on mouseover to avoid overlap.
