Mind Map Generator

Mind maps are visual thinking tools that organize information hierarchically around a central concept. Developed by Tony Buzan in the 1970s, they leverage the brain's natural tendency to associate ideas and think radially rather than linearly. A mind map starts with a central topic in the middle, with major branches radiating outward representing main themes, and sub-branches representing details. This structure mirrors how neural networks work -- ideas connect to related ideas in a web of associations.

Mind maps are effective because they engage both hemispheres of the brain: the left hemisphere processes the words and logical structure, while the right hemisphere processes the spatial layout, colors, and visual relationships. Studies have shown that mind mapping improves memory retention by 10-15% compared to linear note-taking, and enhances creative problem-solving by making connections between disparate ideas visible. They're widely used in education (for study notes and essay planning), business (for meeting agendas and project planning), and personal development (for goal setting and decision-making).

Digital mind mapping offers advantages over paper: unlimited canvas size, easy editing and rearranging, export to multiple formats, and the ability to handle large maps without running out of space. Our tool generates mind maps from indented text or Markdown lists -- you type the outline, and the tool automatically calculates the layout, positioning branches at equal angles around the center and sub-branches along their parent branch. The result is an interactive SVG that can be zoomed, panned, and exported.

Automatic mind map layout is a graph layout problem. The tool uses a radial tree layout algorithm: the root node is placed at the center, first-level children are arranged in a circle around the root at a fixed radius, and each child's subtree is allocated an angular slice proportional to the number of leaf nodes in that subtree. Within each slice, child nodes are positioned recursively, with each level adding another radius increment. This produces a balanced, symmetric layout that minimizes overlapping branches.

The SVG rendering uses Bezier curves for branch connections, creating smooth, organic lines that are more visually appealing than straight lines. Node sizes are proportional to their text length, with font sizes decreasing at deeper levels to maintain visual hierarchy. Colors can be assigned per branch to visually distinguish themes. The SVG is interactive -- nodes can be collapsed/expanded, and the map can be zoomed and panned using standard mouse/touch gestures. Export to SVG or PNG preserves the full map at any zoom level.
