+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+plotly is an R package for creating interactive web graphics via the plotly.js JavaScript library. It provides two main interfaces:
+- `ggplotly()`: Converts ggplot2 objects to interactive plotly visualizations
+- `plot_ly()`: Direct interface to plotly.js for specialized chart types
+
+## Common Commands
+
+### Running Tests
+```r
+# Run all tests
+devtools::test()
+
+# Run visual tests (requires kaleido via reticulate)
+Sys.setenv("VISUAL_TESTS" = "true")
+devtools::test()
+
+# Run a single test file
+devtools::test(filter = "ggplot-bar")
+```
+
+### Package Check
+```r
+rcmdcheck::rcmdcheck()
+```
+
+### Building Documentation
+```r
+devtools::document()
+```
+
+### Visual Testing via Docker
+For consistent visual test results:
+```shell
+docker run -v $(pwd):/home/plotly --privileged -p 3838:3838 cpsievert/plotly-orca
+```
+Access the validation Shiny app at http://0.0.0.0:3838
+
+CI-only visual test run:
+```shell
+docker run -e VMODE="ci" -v $(pwd):/home/plotly --privileged cpsievert/plotly-orca
+```
+
+## Architecture
+
+### ggplot2 to plotly Conversion Pipeline
+
+The conversion from ggplot2 to plotly follows this flow:
+
+1. **`ggplotly()`** (`R/ggplotly.R`): Entry point that dispatches on input type
+2. **`gg2list()`** (`R/ggplotly.R`): Main conversion function that:
+   - Builds the ggplot object to extract computed data
+   - Processes each layer through `layers2traces()`
+   - Processes layout through `layers2layout()`
+3. **`layers2traces()`** (`R/layers2traces.R`): Converts ggplot2 geom layers to plotly trace objects
+4. **`layers2layout()`** (`R/layers2layout.R`): Converts ggplot2 theme/coordinate settings to plotly layout
+
+### Direct plotly Interface
+
+1. **`plot_ly()`** (`R/plotly.R`): Creates a plotly object with trace attributes
+2. **`add_trace()`** and `add_*()` functions (`R/add.R`): Add traces to existing plots
+3. **`layout()`** (`R/layout.R`): Modify plot layout
+4. **`plotly_build()`** (`R/plotly_build.R`): Evaluates lazy attributes and creates final JSON for plotly.js
+
+### Key Modules
+
+- `R/shiny.R`: Shiny integration and event handling
+- `R/subplots.R`: Combining multiple plots
+- `R/highlight.R`: Linked brushing/crosstalk support
+- `R/animate.R`: Animation support
+- `R/kaleido.R`, `R/orca.R`: Static image export
+
+## Testing Patterns
+
+Tests should check the return value of `plotly_build()`:
+```r
+test_that("example test", {
+  p <- plot_ly(x = 1:10, y = 1:10)
+  built <- plotly_build(p)
+  expect_equal(built$x$data[[1]]$x, 1:10)
+})
+```
+
+Visual tests use `expect_doppelganger()` from `tests/testthat/helper-vdiffr.R`:
+```r
+test_that("visual test", {
+  p <- plot_ly(x = 1:10, y = 1:10)
+  expect_doppelganger(p, "scatter-basic")
+})
+```

 # plotly (development version)
 
+## Changes to plotly.js
+
+Upgrades plotly.js from v2.11.1 to v2.25.2 (35 releases). Key new features now available:
+
+* **Multiple legends**: Support for `legend2`, `legend3`, etc. with separate positioning and visibility control
+* **Shape labels**: New `label` attribute for shapes and `label.texttemplate` for parametric shapes
+* **Marker direction**: New `marker.angle`, `marker.angleref`, and `marker.standoff` properties for directional markers
+* **Y-axis positioning**: `shift` and `autoshift` properties to avoid y-axis overlapping in multi-axis plots
+* **Mapbox clustering**: Clustering options and bounds support for `scattermapbox` traces
+* **Equal Earth projection**: New map projection option for geo subplots
+* **Pattern fills**: Pattern support extended to pie, funnelarea, sunburst, icicle, and treemap charts
+* **Editable selections**: Persistent and editable selections over cartesian subplots with `editSelection` config option
+* **Axis label aliases**: `labelalias` for simplified axis label customization
+* **Grid styling**: `griddash` property and minor tick/grid line styling options
+
+Also includes a security fix for prototype pollution and ~90KB bundle size reduction.
+
+See the [plotly.js releases page](https://github.com/plotly/plotly.js/releases) for the full changelog.
+
 ## Improvements
 
 * `save_image()` now works with kaleido v1.0 and higher. (#2447)
