# Create a New Mapping
To design and generate a Semi Structured Transformation mapping, a Semi Structured Transformer must be running and connected to the Studio. Please refer to the [Connecting Transformers](/EGeX4aTAJLlpg9Hh8kfl/getting-started-tutorial/installation/docker/connecting-transformers.md) page if not already done so.
1. Select `Graph.Build`, `Semi Structured Models`, ensure a Transformer is selected from the dropdown, `New Model`.
2. Select `Property Graph`, `Next Step`.
3. In IRI Configuration, select the Schema we created in the previous section and select `Next Step.` Selecting a schema here is not required to create a model. All following steps assume you have created and selected a schema, however you can still follow along by manually entering all values.
4. Name your visualisation `PersonCard` and provide the sample data by using the built-in example `sample.json`.
