Big data usually means slow charts, but not in Observable Canvases. Our optimized queries power fast, interactive visualizations so you can explore more, and wait less, to find insights faster. Learn how we keep charts fast, even with big data:

The hardest part about reusing charts can be getting your data into the expected shape. Learn common data formats consumed by Plot & D3 — and how to transform your data to match — so you can quickly reuse thousands of stunning, interactive visualizations:

When working with big data for BI, data visualizations can be painfully slow to load. That stifles exploration and iteration, which means you might be missing out on business insights. In our new post, learn how we keep charts fast in Observable Canvases:

Update: The Heroku outage we reported on earlier today, which may have temporarily caused issues with data connectors in Observable products, is now resolved.

Due to an ongoing Heroku outage, we are experiencing issues with data connectors. This may impact your use of Observable or cause further disruptions to our services. We will monitor the situation and provide updates as appropriate.

Histograms are incredibly useful, interpretable, and common in BI. But building histograms that work well out of the box for any data is tricky. We share some of the challenges faced, and decisions made, when designing histograms for Observable Canvases:

Data analysts spend their days knee-deep in company data, so they are uniquely positioned to help teammates find, use, and trust analyses that can improve their work. Learn how analysts can contribute to a stronger data culture across their organization:

When data visualization is confined to initial exploration and final storytelling, you can miss out on insights, anomalies, and mistakes that get revealed in between. Learn how end-to-end visual data analysis helps your team uncover insights, and errors:

Most BI tools let you make histograms with one click. So, you might think that designing good default histograms is simple. Turns out, it's harder than it sounds. Learn how we handle common challenges to make better out-of-the-box histograms in canvases:

Including collaborators and stakeholders throughout analysis helps to avoid redundant work, crossed wires, and rehashing decisions at the project finish line. Learn how collaborative analytics gets you from raw data to trusted business decisions, faster:

With end-to-end visual data analysis, you can keep eyes on your data throughout the analysis process. Learn how that helps you discover unexpected value in your data, catch mistakes earlier, and improve cross-functional collaboration:

Collaborative analytics brings data teams and stakeholders into the analysis process from ideation to final product. Discover how that helps you all reach the finish line, faster:
