Sample datasets

Memgraph publishes sample graph datasets that you can load to try Cypher queries, graph algorithms and Memgraph Lab visualizations. Each dataset is a CYPHERL file: Cypher queries that create its indexes, nodes and relationships.

Load a dataset

Load a dataset into an empty database. Loading it again, or into a database that already has data, adds a second copy of its nodes and relationships. To empty the database first, run:

MATCH (n) DETACH DELETE n;

You can load a dataset with mgconsole or with Memgraph Lab.

With mgconsole

If Memgraph runs in Docker, download the dataset’s file and pipe it into mgconsole inside the container. This command loads Capital cities and borders:

curl -fsSL https://download.memgraph.com/datasets/country-capitals/cypherl/dataset.cypherl.gz | gunzip | docker exec -i CONTAINER_NAME mgconsole

CONTAINER_NAME is the name of your Memgraph container: memgraph-mage if you started Memgraph with the Getting started installer. For another dataset, use its file link from the list of datasets.

Check that the counts match the dataset’s row in the list. For Capital cities and borders:

MATCH (n) RETURN count(n) AS nodes;

+-------+
| nodes |
+-------+
| 212   |
+-------+

With Memgraph Lab

In Memgraph Lab, open Datasets in the sidebar, find the dataset and click Load dataset. Lab lists the datasets from the same catalog as the list below.

Available datasets

The datasets are listed by title. The slug is the dataset’s name in its file link, and the file link is what the mgconsole command loads. The same list is available as JSON at https://download.memgraph.com/datasets/items.v1.json, with each dataset’s graph model and sample queries.
