+
+## Overview
+
+This dataset is designed to evaluate the shape understanding capabilities of Multimodal Large Language Models (MLLMs).
+
+## Dataset Splits
+
+Each split corresponds to a different reasoning task and shape identification challenge.
+
+### 🟢 **Regular Polygons (`regular_polygons`)**
+- Task: **Shape Identification & Sides Counting**
+- Description: Consists of images of **regular polygons** (e.g., triangles, pentagons, hexagons, etc.).
+- Example Queries:
+  - *"What shape is in the image?"* 
+  - *"How many sides does the shape in the image have?"* 
+
+### 🟡 **Regular Polygon Pairs (`regular_polygon_pairs`)**
+- Task: **Multi-Shape Reasoning**
+- Description: Images contain **two distinct polygons**. The task involves **identifying both shapes, counting their sides, and summing the total**.
+- Example Query:
+  - *"What are the two shapes in the image, and how many sides do they have in total?"* 
+
+### 🔵 **Abstract Shapes (`abstract_shapes`)**
+- Task: **Complex Shape Recognition**
+- Description: Features **irregular and merged polygons**, stars, arrows, and abstract geometric figures.
+- Example Query:
+  - *"How many sides does this shape have?"*
+
+### 🟣 **Heptagons with Visual Cues (`heptagons_with_visual_cues`)**
+- Task: **Visually-Cued Chain-of-Thought (VC-CoT) Reasoning**
+- Description: Evaluates **VC-CoT prompting** by annotating it with **visual cues** on top of heptagon images.
+- We chose heptagons because it was the most difficult regular polygon for MLLMs.
+- The annotations range from ordered numbers and letters, to random numbers and letters. 
+- Example Query:
+  - *"Observe the shape and list the numbers you see. How many sides does the shape have?"*
+
+### 🔴 **Arrow on Plus with Visual Cues (`arrow_on_plus_with_visual_cues`)**
+- Task: **VC-CoT with Alternative Visual Cues**
+- Description: Similar to the **heptagons_with_visual_cues** split but using **arrow-on-plus shapes** instead.
+- Example Query:
+  - *"Count the total number of numbers associated with the shape’s sides."*
