Breadth-First Search (BFS) Execution on a Sample Graph

Overview

A concise, professional 2‑D animation that walks through the exact step‑by‑step BFS algorithm on a seven‑node graph, mirroring the ByteQuest visual guide. Viewers see the queue and visited set update in real time and understand how duplicate nodes are ignored.

Phases

#	Phase Name	Duration	Description
1	Init	~3s	Show the full graph, place node C at the top center, and display an empty "Visited Set" box and a "Queue (FIFO)" box containing [C].
2	Process C	~4s	Pop C (highlight removal from queue), turn C orange, add it to Visited Set, highlight edges C→A, C→G, C→F in yellow, and append A, G, F to the queue (now [A, G, F]).
3	Process A	~3s	Pop A, turn it orange, add to Visited Set, highlight edge A→B, and enqueue B (queue [G, F, B]).
4	Process G	~3s	Pop G, turn it orange, add to Visited Set, highlight edge G→E, and enqueue E (queue [F, B, E]).
5	Process F	~3s	Pop F, turn it orange, add to Visited Set (no neighbors), queue becomes [B, E].
6	Process B	~4s	Pop B, turn it orange, add to Visited Set, highlight edges B→D and B→G, enqueue D and G (queue [E, D, G]; note duplicate G).
7	Duplicate G Check	~3s	Pop the duplicate G, flash a quick check against Visited Set, recognize it is already orange, and discard it without color change. Queue becomes [E, D].
8	Process Remaining (E then D)	~4s	Pop E, turn orange, add to Visited Set; then pop D, turn orange, add to Visited Set. Queue empties.
9	Final Summary	~3s	Fade in a banner at the bottom reading "Traversal Order: C → A → G → F → B → E → D" and highlight all visited nodes in orange.

Area Descriptions

Area	Content	Notes
Main	The graph with colored nodes, edges, and edge‑highlight animations.	Takes up ~70 % of vertical space; centered.
Queue (FIFO)	Horizontal list box showing current queue order, items added/removed with a slide‑in/out effect.	Placed bottom‑left, fixed width.
Visited Set	Small box listing orange‑colored node labels as they are visited.	Bottom‑right, updates instantly when a node turns orange.

Notes

• Color palette follows the request: background #FDFBF7, node fill #98D8AA, outline #2B5B84, visited orange #FF9F66, queued yellow #F7D060, edge highlight yellow.
• All transitions use simple Manim primitives: Create for initial graph, FadeIn/FadeOut for queue items, Transform for node color changes, Indicate for edge highlights, and a brief Flash (a quick Scale + FadeOut) for the duplicate‑check visual.
• No textual labels on nodes beyond their letters (A‑G); the side panels provide all necessary state information.
• Assumptions made:
  1. Total animation length ~30 seconds, fitting within the 30‑second guideline.
  2. The side panel occupies the bottom 20 % of the frame, split into two equal boxes.
  3. Node positions are arranged for clear edge visibility (standard spring layout).
  4. The final banner appears for the remainder of the scene and then fades out.
• The specification is designed for a single Manim Scene class.
