claudeplot

claudeplot brings the visual language of Anthropic and Claude to ggplot2. It gives you a clean, publication-ready theme, color palettes drawn from Anthropic’s brand and its data-visualization style, discrete and continuous color/fill scales, and palette display helpers. Anthropic’s recommended open typefaces — Poppins for headings and Lora for body text — are bundled and registered automatically.

Installation 

# install.packages("pak")
pak::pak("viniciusoike/claudeplot")

For the bundled fonts to render, install the suggested packages and use a ragg graphics device:

install.packages(c("systemfonts", "ragg"))

Usage 

library(ggplot2)
library(claudeplot)

df <- data.frame(
  model = c("Claude Opus 4.6", "Claude Opus 4.7", "Claude Opus 4.8", "Claude Fable 5"),
  score = c(58.6, 69.2, 80.3, 88.4)
)

ggplot(df, aes(model, score, fill = model)) +
  geom_col(width = 0.7) +
  geom_text(aes(label = score), vjust = -0.5, fontface = "bold") +
  scale_fill_claude_d() +
  labs(
    title = "Agentic coding",
    subtitle = "SWE-Bench Pro success rate (%)",
    x = NULL, y = "Success rate (%)"
  ) +
  theme_claude() +
  theme(legend.position = "none")

Color scales

Discrete (_d) and continuous (_c) scales are available for both color (and colour) and fill:

scale_color_claude_d(palette = "claude")     # discrete, vivid benchmark palette
scale_fill_claude_d(palette = "brand")        # discrete, muted brand accents
scale_fill_claude_c(palette = "oranges")      # continuous, sequential
scale_color_claude_c(palette = "orange_blue") # continuous, diverging

Palettes

Explore palettes with show_claude_palette() (one palette) and show_claude_palettes() (all of them):

The families are qualitative (claude, brand, warm, cool, neutral), sequential (oranges, blues, greens, grays), and diverging (orange_blue, green_orange, spectral). List them with claude_palette_names().

Fonts

claudeplot bundles Poppins and Lora (both SIL Open Font License). They are registered with systemfonts when the package loads. Check the status with:

If the fonts are unavailable, theme_claude() falls back to generic "sans" and "serif" families.

How this package was made

claudeplot is itself a small experiment. It was built on the release day of Claude Fable 5, as a test of what Claude (the model writing this) can do end to end: researching Anthropic’s brand and chart style, designing the palettes and theme, writing the package, getting it to pass R CMD check --as-cran with zero notes, and shipping the GitHub repo and pkgdown site.

It was produced largely from a single prompt, with the help of a few useful templates and reference packages. Treat it as a demonstration rather than a battle-tested library — though the goal was very much to make it real.
