Reflex AI has launched XY, an Apache-2.0 Python charting library for interactive 2D visualization. Most Python charting stacks create one drawable object per row, so previous a number of hundred thousand factors, render, hover, and zoom degrade. XY strikes the work right into a native Rust core, sends the browser typed binary buffers as a substitute of JSON, and attracts with WebGL2. Within the phrases of the benchmark, XY holds 0.071 s at 10,000 factors and 0.081 s at 100 million. It ships as pip set up xy and requires Python 3.11 or newer.
Is it deployable
XY is early alpha at model 0.0.1. It ships as pip set up xy and requires Python 3.11 or newer.
That maps to a transparent deployment envelope. Startups and mid-size knowledge groups can undertake it now for inner analytics, notebooks, and shareable artifacts. Regulated enterprises ought to pilot it relatively than put it on a customer-facing crucial path. Match is strongest the place row counts are the precise bottleneck: quantitative finance (tick knowledge), genomics and bioinformatics (Manhattan plots, allele-frequency scans), observability and telemetry, astronomy, and geospatial analytics. Right here is learn how to set up it in 1 line.
Explainer
How the illustration ladder works
XY retains canonical f64 columns in a ColumnStore in Python and picks a rendered illustration per hint. Present defaults begin M4 decimation above 10,000 rows for lengthy ordered traces, and automated scatter density above 200,000 factors. Density grids default to 512×384 cells. The docs are specific that these are pre-1.0 coverage thresholds, not API ensures.
As a result of precise values keep in Python, hover, choice, and choose() nonetheless resolve unique rows when the lively tier has a precise mapping. Zooming right into a slim window returns precise seen factors for a padded aligned window, and close by pans render from that cached window with out one other request. Reflex is cautious to not overclaim right here: density is natively binned and GPU-rendered, not an all-GPU ingest pipeline, and ingest, binning, and decimation nonetheless scale with supply row rely.
Efficiency
The benchmark drives each library by way of an actual browser and stops the clock solely when the canvas is verified right and secure throughout 10 byte-identical frames. Measurements come from one Apple M5 Professional, one run per cell.
| Factors | XY | Matplotlib (WebAgg) | Plotly (scattergl) |
|---|---|---|---|
| 1M | 0.084 s | 0.357 s | 0.614 s |
| 10M | 0.083 s | 2.804 s | 3.367 s |
| 50M | 0.076 s | 13.385 s | ✕ |
| 100M | 0.081 s | ✕ | ✕ |
That could be a said 34× speedup at 10M and 177× at 50M. Peak Python-side reminiscence at 10M is 0.32 GiB for XY in opposition to 0.84 GiB for Matplotlib and 1.86 GiB for Plotly. With density=False, XY nonetheless attracts 100M precise markers in 1.343 s on 5.26 GiB. Reflex additionally stories rendering the total OpenStreetMap dataset — 10 billion factors.
A ten-million-point interactive scatter exports to 258 KiB of HTML, versus a said 259 MiB for the Plotly equal. The payload stays close to 258 KiB from 1M by way of 100M rows.
API floor and integration
Charts are composed declaratively from marks, axes, legends, tooltips, and annotations. Fourteen chart households ship at the moment, together with scatter, line, space, histogram, field, violin, ECDF, heatmap, hexbin, and contour. Styling accepts CSS and Tailwind lessons by way of secure DOM slots. For migration, import xy.pyplot as plt runs widespread Matplotlib pyplot code, although the compatibility information notes not the whole lot is supported. A separate reflex-xy adapter turns any chart right into a Reflex part with no JavaScript or iframe.
Key Takeaways
- XY holds ~0.08 s render time from 10k to 100M factors by drawing screen-bounded representations, not per-row markers.
- Rust core plus binary transport cuts a 10M-point interactive export to 258 KiB in opposition to Plotly’s 259 MiB.
- Actual f64 columns keep in Python, so hover, choice, and zoom drilldown nonetheless return unique rows.
- Deployable at the moment for notebooks, inner dashboards, and shareable HTML; model 0.0.1 alpha argues in opposition to crucial paths.
- Greatest match is finance, genomics, telemetry, and astronomy, the place sampling earlier than plotting is the present default.
