Dual-Boiler Espresso Machines — Original Scatterplot, Fixed

The same price-versus-steam-capacity scatterplot as the original report — same axes, same marks, same encodings — now laid out without overlapping labels and with the legend moved out of the plot. 42 dual-boiler model entries; all 42 carry a steam-boiler figure in litres, 9 also resolve a typical explicit US asking price in USD. The 33 entries without a resolved price stay visible in a compact strip beneath the scatter and in the table.

33 entries with a resolved steam-boiler figure but no defensible explicit US price — placed by steam litres only, hover any mark for what is known
The priced field spans $1,940 for the Rancilio Silvia Pro X with a 1.0 L steam boiler up to $6,990 for the Rocket Bicocca at 1.5 L — price and steam capacity do not move together.espressosetupbuilder.com
At $2,250 the LUCCA A53 Direct Plumb already pairs a rotary pump, plumb-in and a 2.5 L steam boiler — the same steam capacity as the $3,800 A53 Pro.clivecoffee.com
The biggest steam boiler among priced entries is the La Marzocco Linea Mini at 3.5 L and $6,600, one of only two priced machines with pressure or flow profiling.clivecoffee.com
Among the 33 unpriced entries the La Marzocco GS3 family matches the Linea Mini's 3.5 L steam boiler, with plumb-in, paddle control and profiling on the GS3 MP.lamarzocco.com

Data: 42 dual-boiler prosumer espresso-machine entries, one row per searched model entry, researched 2026-08-27 from live manufacturer, retailer and review pages. Price is a typical explicit US asking price in USD found on the page, not a converted global MSRP; the counts of 42 entries, 9 with a price and 42 with a steam figure come from precomputed aggregates carried on the rows. A dash marks a value that was not defensibly resolved, not a feature that is absent. Control type and dimensions were cut from the table for width — control type appears in the hover tooltips where resolved. This page rebuilds the original scatter with its exact encodings, fixing only the overlapping labels and in-plot legend.
