myIO: Interactive Data Visualizations Using 'd3.js'

Create interactive 'd3.js' visualizations from R with built-in statistical transforms. Computes confidence intervals, regression fits, LOESS smoothing, moving averages, error bars, and uncertainty visualizations (quantile dot plots and fan charts) in R and renders them as composable chart layers via 'htmlwidgets'. Supports 36 chart types including boxplots, violin plots, Q-Q diagnostic plots, calendar heatmaps, survival curves, and group comparisons with pairwise significance testing. Also provides a machine-readable chart specification schema with validators so that large language model agents can author and verify charts. Works in 'RStudio', 'Shiny', and 'R Markdown'.

LLM Tool Calling
The problem this solves | New to "tool calling"? | A first example | What you can rely on | Checking specs against real data | Checking function calls | The six tools | The repair loop | Wiring it into an assistant (MCP) | What validation guarantees — and what it does not

Migrating from plotly to myIO
Why switch from plotly? | Side-by-side: 8 common patterns | 1. Basic scatter plot | 2. Line chart with multiple series | 3. Bar chart | 4. Histogram | 5. Box plot | 6. Regression line with CI band | 7. Statistical annotations | 8. Dark mode theming | What myIO does that plotly can't | What plotly does that myIO doesn't

Why myIO
The problem | What myIO does differently | 1. Confidence intervals as first-class layers | 2. One-line regression with R² annotation | 3. Composable transforms | 4. Composite charts expand into primitives | 5. Error bars with one line | Design philosophy | 6. Bidirectional I/O | When to use myIO | When to use something else
