In version 1.4 Cosmos introduces features like curved links, enhanced node focus/hover distinctions with new configurations, options for initial zoom level and disabling zoom/simulation, and more.

cosmos-curved-links

What's new:

  • Curved Links: The curvedLinks config parameter turns line curvature on/off.

  • New onTick callback arguments: The hovered node, index, and nodePosition are now available as second, third, and fourth callback arguments.

  • Hovered and focused nodes introduced: We've separated the highlighted nodes into two categories: hovered and focused nodes. We also added new methods to control the focused node such as setFocusedNodeById and setFocusedNodeByIndex. Additionally, we have introduced new configuration parameters that allow for more customization, such as renderHoveredNodeRing, hoveredNodeRingColor, and focusedNodeRingColor. These new changes will be available alongside the old configurations to ensure compatibility until version 2.0. For more detailed information, please see our wiki page.

  • Adjusted transparency of the hovered and focused node's ring:** The transparency of the hovered and focused node's ring is now inherited from the parent node.

  • Assigning the initial zoom level to the graph when it is first created: The `initialZoomLevel' configuration parameter can be set once during graph initialization.

  • Disable Zooming. If the disableZoom configuration parameter is set to true, zooming in and out using the mouse wheel is disabled.

  • Cosmos can be run without the simulation, e.g. if you just want to visualize your data set with provided node coordinates. Use the disableSimulation config parameter to turn on that behavior (please note that it can be set on graph initialization only).

Fixes:

  • Smart destruction of WebGL buffers and frame buffers and preventing a zero-sized texture from attaching to a WebGL frame buffer.

  • Cosmos will not crash if there are no nodes or links.

  • Fixed the fitView method execution, when calling before the animation starts.

  • Adjusting spaceSize if it exceeds the WebGL limit (#49 (comment)).

  • Cosmos can now run the simulation even if the graph contains only nodes and no links.

  • We made the graph property public in the main Graph class (where the data processing takes place).

  • Added a second argument - index to the config accessor functions nodeSize and nodeColor.

Optimization

  • We have improved the method for finding the hovered node to minimize the chance of slowdowns or lags.

Other

  • We've also added a citation file that you can use if you use Cosmos or Cosmograph.
