afcharts vs NGINX
A side-by-side editorial comparison of afcharts and NGINX — release velocity, themes, recent moves, and the top alternatives to consider.
afcharts vs NGINX: at a glance
What is afcharts?
UK government chart styling in ggplot2, chasing ggplot2 v4 and stretching its palette to five.
afcharts supplies the UK Analysis Function's chart styling for ggplot2, as a theme, colour and fill scales, and a use_afcharts() call that applies the styling globally. Version 0.5.1 extends the sequential palette to five shades so it can carry quintile data such as deprivation bands, renames the na_colour argument to na.value, and adds a reset argument to switch the styling back off. The package began as a first release derived from sgplot and has had three releases in roughly two years.
What is NGINX?
nginx returns to feature work with PROXY v2 upstream writes, and quietly adds JSON to core.
1.31.4 is the first mainline release in months that is not primarily a CVE response. It adds PROXY protocol version 2 write support for stream upstreams, special-cases the Host header for HTTP and gRPC upstreams, and tightens QUIC flow control on RESET_STREAM final sizes. Underneath those, core gained data model and JSON serialization libraries that nothing in this release consumes.

UK government chart styling in ggplot2, chasing ggplot2 v4 and stretching its palette to five.
◆ Current state
afcharts supplies the UK Analysis Function's chart styling for ggplot2, as a theme, colour and fill scales, and a use_afcharts() call that applies the styling globally. Version 0.5.1 extends the sequential palette to five shades so it can carry quintile data such as deprivation bands, renames the na_colour argument to na.value, and adds a reset argument to switch the styling back off. The package began as a first release derived from sgplot and has had three releases in roughly two years.
◆ Where it's heading
The work splits between palette design and keeping the styling composable. On the design side the sequential palette growing to five shades is driven by a specific reporting need rather than aesthetics, since quintiles are a standard unit in UK official statistics. On the mechanical side, the na.value rename was forced by ggplot2 v4.0.1, theme_af() now respects options set by an earlier use_afcharts() call, and a reset argument acknowledges that global styling needs an off switch. These are the problems a styling package hits once people use it inside larger documents.
◆ Prediction
Expect continued adjustment to ggplot2 v4, since the na.value rename is unlikely to be the only argument affected, and further palette work driven by the reporting formats government analysts actually publish. As a sibling to aftables in the same Analysis Function family, it is likely to keep tracking that guidance rather than setting its own direction.
NGINX
2.5INFRA · APIS
nginx returns to feature work with PROXY v2 upstream writes, and quietly adds JSON to core.
◆ Current state
1.31.4 is the first mainline release in months that is not primarily a CVE response. It adds PROXY protocol version 2 write support for stream upstreams, special-cases the Host header for HTTP and gRPC upstreams, and tightens QUIC flow control on RESET_STREAM final sizes. Underneath those, core gained data model and JSON serialization libraries that nothing in this release consumes.
◆ Where it's heading
The five preceding releases were security releases: three CVEs in July across both branches, an HTTP/2 and gRPC buffer overflow and an HTTP/3 use-after-free in June. Against that run, 1.31.4 reads as the project returning to feature work, with F5 contributors visible across the stream and upstream changes and four first-time contributors landing fixes. The JSON and data-model libraries are the item worth watching, since general serialization is not something a proxy needs for proxying.
◆ Prediction
Those libraries have no consumer in this release, so the plausible next move is a feature that uses them, such as structured status output or configuration, rather than another round of parser hardening.
