v1.2

Changes in 1.2.0

Breaking changes

• Removed the show_hover_tooltip parameter from render(). The visualization now shows a detail side panel for selected nodes and relationships, replacing the previous hover tooltip.
• Nodes are colored by default by their caption. Use VG.color_nodes(field="caption", colors=[neo4j_viz.colors.NEO4J_COLORS_DISCRETE[0]]) to apply the previous coloring.

New features

• Nodes are now automatically colored by their caption (label) in the JavaScript visualization. This works out of the box without needing to call color_nodes(), and applies regardless of how the graph was created. Explicit colors set via color_nodes() or directly on nodes take precedence. There is no longer a limit on the number of unique labels for auto-coloring.
• New Zoom to fit button in the visualization.
• New render_widget() method on VisualizationGraph returns a GraphWidget (anywidget) for interactive two-way data sync in Jupyter environments (JupyterLab, Notebook 7, VS Code, Colab).

Improvements

• Migrated JavaScript visualization from @neo4j-nvl/base to @neo4j-ndl/react-graph React component.
• Migrated build system from Webpack to Vite.
• Added anywidget integration as the primary rendering path for Jupyter environments.
