silx settles into maintenance a release after its PySide6 migration
A side-by-side editorial comparison of AgencyAnalytics and vellumplot — release velocity, themes, recent moves, and the top alternatives to consider.
AgencyAnalytics is turning its assistant into scheduled agency staff work, not a chat box.
The release cadence is weekly and heavily weighted toward AgencyAI. Skills landed in early August as named, runnable agency tasks; scheduling followed, letting those requests run on a cadence and post results into the client's conversation. Around them sit portfolio-management improvements — client tags, report share history, advanced metric filtering — and a consolidated Data tab feeding the assistant's context.
vellumplot tags its first release with a bet most R grammars don't make: the static figure and the widget are the same object.
A new grammar of graphics built on the vellum vector engine, developing fast — ten releases in roughly three weeks — and now at its first tagged release. The distinguishing architectural claim is that the compiled plot is the scene, so a static export and an interactive widget cannot drift apart, and that it renders without a graphics device because vellum measures text itself. Accessibility is treated as a first-class output rather than an afterthought: tagged PDF with a navigable structure tree and alt text, a plot_lint() check, and colour-vision-deficiency simulation at render time.

Every recent release either gives AgencyAI more to read or more autonomy in when it runs. The Data tab consolidation, the AI Tracker add-on for AI search visibility, and now scheduling all point the same way: the platform is being positioned to produce the recurring client deliverables an agency would otherwise assign to a junior analyst.
Expect scheduled AgencyAI output to gain delivery paths beyond conversation history — into reports or client-facing sends — given the existing report scheduling and share infrastructure.

The release sequence shows a grammar filling in ggplot2-parity features and specialist marks in parallel. Parity work landed as secondary axes, rich legend titles, and Sankey styling; the specialist end added categorical datashading, image marks, flow maps and edge bundling for dense graphs. Version 0.7.0 shows a willingness to break early — vsunburst() was removed outright in favour of one vhierarchy() constructor covering sunburst, icicle, treemap and circlepack — which is the right time to do it and suggests the API is still being consolidated toward fewer, more general constructors.
Expect more consolidation of near-duplicate constructors under type arguments and continued expansion of the declarative interactivity introduced in 0.7.0, now that the first tagged release has fixed a public API surface.
