- Introduced a new feature to visualize the Document Object Model (DOM) tree of the loaded web page. - Implemented keyboard shortcut (Ctrl+Shift+D) for generating and displaying the DOM graph. - Added core implementation files: - src/debug/dom_graph.py: Handles generation and rendering of graphs in DOT and SVG formats. - Created templates and documentation for the new feature, including: - docs/DOM_VISUALIZATION.md: Overview and usage instructions. - docs/DOM_GRAPH_UX.md: User experience design documentation. - Allowed the visualization to open in a new browser tab instead of an external viewer. - Enhanced visual representation through color coding of different HTML elements. - Implemented comprehensive tests for graph generation and page rendering. - Updated README.md to include usage instructions for DOM visualization. - Included test_holder.html as an example test page. - Modified various components in the browser to integrate tab management and enhance the graphical rendering experience.
