## Dataset Description

- **Homepage:** https://eezy.com


### Dataset Summary

This is a synthetic dataset containing randomly-generated SVGs with various shapes
### Supported Tasks and Leaderboards

NA

### Languages

NA

## Dataset Structure

The dataset is composed of 4 base domains, plus a 'mixed' domain that is a superset of the other 4:
* `circles` - only circles
* `squares` - only squares
* `squares_and_circles` - circles and squares present in the same svg
* `scer` - squares, circles, ellipses, and rectangles present in the same svg
* `mixed` - an aggregation of all of the above

### Data Instances

There's stuff there

### Data Fields

Each example has 4 fields:

* `svg` - the raw svg as a string
* `png` - a raster rendering of the svg with a white background
* `object_mask` - a black/white mask that defines the outlines of the svg objects
* `layer_mask` - a greyscale mask that defines layers of svg objects - overlap regions are brighter. Created by making all the objects white and semi-transparent
* `segments` - a numpy array in the shape `(N,512,512), dtype='bool'` where N is the number of svg objects. The array is a mask of each object with `True` in the area of the object

### Data Splits

Train & validation include the layer and object masks, test does not

## Dataset Creation

Generated by randomly inserting objects into an SVG.

### Curation Rationale

Objects should have at least 50% of their bounding box visible - i.e. no big circle completely obscuring a little circle

### Source Data

`/dev/urandom`

#### Initial Data Collection and Normalization

NA

#### Who are the source language producers?

NA

### Annotations

see [Data Fields](#data-fields)

#### Annotation process

see [Data Fields](#data-fields)

#### Who are the annotators?

Imagemagick/pysvg

### Personal and Sensitive Information

Unlikely

## Considerations for Using the Data

Please do not use for world domination.

### Social Impact of Dataset

NA

### Discussion of Biases

Dataset is highly biased against triangles and concave shapes

### Other Known Limitations

Color selection is pretty limited.

## Additional Information

### Dataset Curators

### Licensing Information

CC-BY

### Citation Information

Link it I guess?

### Contributions

Thanks to [@aleksclark](https://github.com/aleksclark) for adding this dataset.
