Observable Framework 1.3 🆕 integrates Interactive Data Lab’s Mosaic vgplot, which can concisely expressive performant coordinated views of millions of data points.

Framework’s Mosaic integration uses the same sql front matter option as our @duckdb-backed SQL code blocks, so you can query the same data sources through both Mosaic and SQL.

We made our DuckDBClient noticeably faster by not streaming queries, and by representing results natively as Apache Arrow tables (instead of materializing array-of-objects).

Framework now lets you register interpreted languages for data loaders in your config! And we support Java, Julia, and PHP by default. To add Perl and AppleScript: export default { interpreters: { ".pl": ["perl"], ".scpt": ["osascript"] } };

1.3 also adds a cleanUrls config option, a `dark` reactive variable, auto-linkification to Markdown, and more. Please upvote, file issues, open discussions, etc. We love hearing from you!

@observablehq @uwdata you really cooked with this release folks

@uwdata love the shipping speed!

@uwdata I love the velocity of this project. Happy to be an early adopter.

@uwdata Quite impressive

@mael_p @uwdata Not directly. But Mosaic vgplot builds on Observable Plot and we’re actively contributing there.
