v0.3.7

Features 🚀

• Nodes are expanded to aesthetically fit all connections if not enough room with default dimensions
• Arrowhead labels are considered in autolayout and avoid overlaps as much as possible

Improvements 🧹

• Pairs of nodes prefer horizontal arrangements given multiple connections with labels

Bugfixes ⛑️

• Fixes a rare bug using near to a node in a tree structure
• Fixes a rare bug positioning nested node clusters
• Fixes a rare panic involving edge labels

v0.3.6

Compatible with D2 0.4.1 onwards.

Improvements 🧹

• Improves edge routing between hierarchies and non-hierarchies

v0.3.5

Way, way faster!

Improvements 🧹

• Edge routing is up to 31% faster
• Improves layout of clusters
• Node placement is up to 2x faster
• Up to 41% less memory usage
• Avoids clustering nodes when their sizes are disproportionately different
• Prevent image labels from being placed over the image in some cases

Bugfixes ⛑️

• Fixes a rare bug where container children place outside of container
• Fixes self-loop sizing on containers
• Fixes node drift in certain cases
• Fixes an issue where unlabeled connections could completely overlap each other
• Fixes a bug with node alignments

v0.3.4

This release brings massive improvements in performance. Screenshot from our internal benchmarks on a batch of tests, comparing this release vs the last:

As a result of this, TALA by default now executes 3 runs in parallel with different seeds, and picking the best one for you. This should produce better results at a much higher rate!

This release requires D2 0.2.6

Features 🚀

• You can now pass in multiple seeds, and TALA will race multiple layout runs with
  different seeds, choosing the best outcome. See the TALA Manual for more.

Improvements 🧹

• Improves subgraph compaction giving space for better edges
• Improved edge routing for clustered nodes
• Significantly speeds up edge routing with many edges
• Significant performance improvements
• Uses up to 56% less memory for layouts with sql_tables

Bugfixes ⛑️

• Fixes a rare condition that allowed nodes with self loops to escape their containers
• Fixes edge from container going through descendants
• Fixes a bug that could cause some asymmetrical edge routing
• Fixes container shapes sometimes not having enough padding to fit icons
• Fixes the alignment of nodes connected to sequence steps
• Fixes the placement of clustered nodes connected to sequences

Breaking Changes

• tala-seed changed to tala-seeds. You can still continue to pass in a single number,
  same as before. But the name change is reflective that it can now take in multiple
  seeds.

v0.3.3

Improvements 🧹

• Clusters are sized such that labels always have enough room.
• Improves shape-specific label position preferences (for example, parallelograms now prefer placing labels within the shape).

Bugfixes ⛑️

• Nested node labels no longer overlap container boundaries occasionally

v0.3.2

Label positions improve significantly!

Before

After

Improvements 🧹

• Improves edge label positioning
• Improves node label positioning

Bugfixes ⛑️

• Fixes a rare bug that could affect edge routes
• Fixes a bug with top and left keywords in nested containers that could cause layout errors

v0.3.1

• Hotfix to last release where the plugin would give an error saying container self-edges were not allowed when they are.

v0.3.0

TALA 0.3.0 implements position-locking to give control over parts of the diagram where you need it. This is an advanced feature that opens up a world of possibilities to create small bubbles of customized layouts and combine it with autolayout. For example, here's a legend:

Legend: {
  top: 0
  left: 0
  blue: "" {
    width: 20
    height: 20
    left: 0
    top: 0
    style.stroke: black
  }
  blue-explanation: Actions {
    shape: text
    left: 50
    top: 0
  }

  green: "" {
    width: 20
    height: 20
    left: 0
    top: 50
    style.fill: honeydew
    style.stroke: black
  }
  green-explanation: Intermediate artifacts {
    shape: text
    left: 50
    top: 50
  }
}

We're excited to see all the creative diagrams this enables!

Features 🚀

• top and left positions implemented.

Improvements 🧹

• ~30% faster for large, connected diagrams
• Much faster gap normalization for all diagrams
• Bin-packing algorithm improved to reduce whitespace between non-connected subgraphs

Bugfixes ⛑️

• Fixes label placements avoiding connections that weren't actually obstructing
• Fixes a rare panic that could with cluster nodes
• Edges could sometimes route through nodes that were not part of its subgraph
• Edges between containers that were perfectly aligned was sometimes unable to find a route.

v0.2.15

Improvements 🧹

• Padding reduced on containers to align with more compact look and feel of D2 0.2.
• sql_table routing switched from using hierarchical layout engine to orthogonal.
• Diagrams with multiple subgraphs are more compact.
• Much improved hierarchical alignments for diagrams where connections skip hierarchy levels (e.g. a node in the first row connected to another 2 rows down).

Bugfixes ⛑️

• Fixes an issue with hierarchy leveling where connections between two nodes of the same level could occur.
• sql_table connections where column is not specified no longer always points to first column.

v0.2.14

Improvements 🧹

• Improves cluster arrangements and edge routing
• Positions shapes closer to neighbors outside its own container
• Reduce edge routing runtime by ~10%
• Improves hierarchy algorithm to place objects at different levels when appropriate

Bugfixes ⛑️

• Fixes a rare panic while reducing gap between nodes
• Fixes a rare panic with sequences (connected step shapes)
• Fixes a rare panic with clusters
• Fixes a rare panic when children of a container are connected to different childrens of different containers
• Fixes an error where a connection route sometimes couldn't be found from a center step of a sequence
