Release notes

• We’ve officially launched AI for canvases. Read the announcement.

• You can now make canvases with Databricks data sources.

• Added a beeswarm chart type.

• Adding a child to a node in a frame now creates the child in the frame.

• Sankey diagrams can now be sorted alphabetically or by size.

• The From nodes’ table selector now matches the left data panel and includes search.

• AI now stops its work if you switch pages and stops more reliably.

• The old deprecated Join node has been removed. If you have canvases still using the old Join node, you will have to reconnect their input edges to fix them.

• You can now make canvases with Postgres data sources.

• Expanded the choropleth to support either a U.S. or world base map.

• Added a dot strip chart type (a scatterplot with ordinal y and quantitative x).

• Sankey diagrams now default to sizing by count.

• Sankey diagrams now have options for filtering nulls and merging source and target.

• AI now understands more about bar charts, scatterplots, and treemaps.

• AI now remembers its last prompt and output even if you’ve panned away.

• AI now identifies nodes primarily by the same names you see and edit.

• Improved handling of BigInt and Time units in DuckDB sources.

• Fixed issue where you could add a broken DuckDB table before it had loaded.

• Fixed histograms’ multiline brush labels in Safari.

• The join node can now join to any table on the canvas (instead of just to database tables).

• Line charts support new options for binning intervals, axis labels, and axis ticks.

• Added a Sankey diagram chart type.

• AI is now more concise.

• AI now highlights questions for you to respond to.

• The JavaScript node’s CSS now matches notebooks’ CSS.

• Uploading a file to a DuckDB canvas no longer immediately adds the table to the canvas. (Click “+” beside a table in the data panel to add it.)

• Fixed AI to see nodes inside of frames.

• Fixed SQL parsing to support trailing comments.

• Fixed autocomplete clipping in JavaScript and SQL nodes.

• Fixed SQL and Derive nodes to re-run children after filtering.

• Nodes are now named by default. (Double-click the name in the header to edit.)

• You can now add a SQL node querying the selected node from the “+” menu.

• AI now puts its canvas work in a frame labeled with your prompt.

• AI now sees more detail to match what you see in column summaries.

• Updated fonts (Draw, Sans, Serif, and Mono) to better match notebooks.

• Fixed bug where summary charts of time columns would fail to load.

• Fixed Snowflake “Edit database” settings to remember password until reset.

• The default font on canvases is now sans-serif instead of handwritten script.

• You can now toggle column summary charts in tables’ “⋮” menu (upper right).

• Duplicating nodes now maintains upstream inputs.

• Line charts’ y-axes now include 0 if the data’s minimum is a small fraction of the maximum.

• AI now takes better advantage of available chart options.

• AI now shows an error when it cannot connect.

• Categorical column summaries now alphabetize values with equal counts.

• Nulls in column summaries now have a hatched background, and “Others” are cross-hatched.

• Long column names in the data pane now truncate instead of wrapping.

• Fixed dates from Snowflake sources to display in UTC instead of local time.

• Fixed tables losing scroll position when blurred.

• Fixed syntax highlighting in SQL nodes.

• Fixed intraday brushing of line charts.

• Added new line charts with smart collision-avoidant labeling.

• Temporal histograms now have configurable bin interval and rolling averages.

• Bar charts now have configurable sorting.

• Density plots now have configurable scales.

• The AI now understands top column values and more about histograms.

• The AI now understands which nodes depend on which.

• The AI’s filtering is more reliable and adds new nodes instead of editing existing ones.

• The AI can now use the UI to group, limit, and sort rows, and to derive new columns.

• The AI no longer writes SQL and JavaScript nodes by default. (Toggle them in Menu → “Developer tools” → “Show AI options”.)

• You can now press Shift-Return to run a code node.

• You can now set arrows to the “elbow” style. (tldraw v3.13)

• Fixed numbers and bullet points disappearing in lists. (tldraw v3.13)

• Fixed scrolling nodes’ side panels, including SQL and JavaScript editors.

• Fixed some transient errors while loading charts.

• Fixed some bugs in filtering histograms.

• The AI can now add columns based on existing tables.

• Charts more smoothly update to reflect new data.

• Cleaned up some unused, outdated, or broken menu items.

• Fixed creating a chart from a temporal column summary.

• Fixed scrolling in code nodes.

• Fixed adding database tables with zero rows to the canvas.

• Temporal histograms can now be weighted by a “value” channel.

• Stacked bar charts now collapse less frequent categories into an “Other” category.

• Histogram axis ticks now avoid colliding with each other.

• Charts’ PNG downloads now include the title and caption.

• AI can now use the new scatterplots.

• You can now press the up and down arrow keys in the AI prompt to navigate its history.

• Adding a new node to the canvas now places it in an emptier initial spot.

• Fixed zooming the canvas while pointing at a selected node.

• Fixed errors in the initial states of nodes.

• Fixed bug where “New canvas” modal listed workspaces without access to the beta.

• The chart node has been redesigned, and its options have expanded.

• The AI can now make more kinds of charts and filter existing nodes.

• AI options are now hidden behind Menu → “Developer tools” → “Show AI options”.

• The data panel now shows more information about your data source’s schema.

• The JavaScript node can now render the output of expressions, not just statements.

• Creating a new node now selects the node.

• Nodes better detect stalled data loading and show clearer errors.

• Fixed uploading images to the canvas.

• Fixed bug where dropdown menus wouldn’t close.

• Fixed the left outliers bin for ordinal histograms.

• Fixed downloading charts as PNG.

• Queries are now more reliable.

• The Plot node is now known as the JavaScript node.

• The data panel in the upper left has been refined.

• The button to add a SQL node has moved to the bottom toolbar.

• The AI can now see nodes’ rows of data.

• Null values are better filtered out of summary histograms.

• The hi-res heatmap now supports negative numbers.

• The “New canvas” modal now only lists eligible data sources.

• Early beta access now applies to workspaces, not users.

Early access is now available for Observable Canvases, a collaborative, visual medium for exploring, analyzing, and communicating with data. Learn more
