Challenges underlying the humble data join

Observable @observablehq.com · 15d

Data joins are everywhere in analytics, but it's tricky to build UI-based joins in a reactive canvas.

In Observable Canvases, we’ve built robust joins that avoid SELECT *, deduplicate columns, and handle upstream changes. Learn more:

Joins are a cornerstone of data wrangling, but are surprisingly challenging to build as UI-based operations. Get a behind the scenes look into why joins are hard, and how we handle them in Observable…

Observable Notebooks Data loaders | Observable

Observable @observablehq.com · 16d

We recently announced Observable Notebooks 2.0 with a new, open notebook file format + desktop app. Now, we’ve added Python & Node.js data loaders — special cells that run at build time, for better stability and performance.

Learn more 👉

Data loaders are special cells that run “ahead” at build time via an interpreter, rather than “live” when you view a notebook in the browser. Data loaders are useful for preparing static data,…

Slow-loading tables and overworked browsers can bog down analysis when you're exploring large datasets. In our new post, we explain how table virtualization in Observable Canvas keeps data work fast and fluid — even with big data, and when viewing complex, branching analyses: buff.ly/7cfqsQA

Why has the promise of self-serve analytics failed?

Observable @observablehq.com · 28d

Self-serve analytics sounds great — that is, until tools overwhelm or constrain users, and adoption tanks. Our VP of Sales, Trevor Eddy, shares how collaborative analytics delivers insights and finally fulfills the promise of self-serve BI:

There was so much hype around the promise of self-serve analytics: data-driven insights, efficiency gains and competitive advantage. In this post, we outline why self-service analytics has failed,…
