Hello! Is there a way in dagit to show asset lineage between jobs? I have a contrived example where I am fetching vehicle manufacturers information and then uploading it to Snowflake. Then a 2nd job that just fetches the manufacturer IDs from that table. That 2nd job is triggered with an asset sensor where the "triggering" asset that it is monitoring is the "upload_mfrs_to_snowflake" asset from the 1st job.
But in dagit, it doesn't visually show the relationship between the 2nd job's asset and the 1st job's asset. Below is what I was expecting or hoping dagit would show:

Hi @Daniel Kim you can specify the relationship between assets by specifying as inputs. So you could have something like this
Copy code
def manufacturers():
    # gets mfrs
    return mfrs

def manufacturer_id_list(manufacturers)
    # get id_list from manufacturers
    return id_list
and then you can still make your jobs from individual assets for your sensors, and the relationship should show up in dagit too

@jamie Ah gotcha! I should have mentioned that I thought that since in my asset_sensor definition, it specified the asset_key to monitor via asset_key=AssetKey("upload_mfrs_to_snowflake"), I thought it would automatically build that relationship in dagit. But I see now that you're saying I still need to explicitly define the relationship.

btw, if your downstream asset doesn't need Dagster to load the values with an IO manager,
to specify the dependency in a lightweight way
