# Visualize Data

> Turn enriched workflow output into quick charts and review views for GTM decisions. Use it for a first run, result review, and safe scaling.

Job: see what your workflow produced before you hand it to sales, marketing, or ops.

The SDK is not only for enrichment. It should help you answer:

* Which accounts are new this week?
* Which segments have the strongest signal?
* Which titles need a different workflow?
* Which rows failed and need human review?
* Which accounts should go to Salesforce now?

## Start with an output CSV

Most workflows should write an output file:

```bash theme={null}
deepline plays run weekly-new-accounts.play.ts \
  --csv accounts.csv \
  --watch

deepline runs export <run-id> --out output/accounts-enriched.csv
```

Open the file first. You are looking for boring things:

| Check                | Why                                        |
| -------------------- | ------------------------------------------ |
| row count            | Make sure no records disappeared           |
| segment              | Know which workflow path each account took |
| signal columns       | See why the account is interesting         |
| owner or next step   | Confirm where the record goes next         |
| error/review columns | Separate good output from uncertain output |

## Make a quick chart in Python

Use this when you want a fast view before building anything permanent.

```py theme={null}
import pandas as pd

df = pd.read_csv("output/accounts-enriched.csv")
print(df["segment"].value_counts())
print(df["next_step"].value_counts())
```

That is enough to answer: “Did this workflow find the kind of accounts we wanted?”

## Common GTM views

| View                | Useful when                                     |
| ------------------- | ----------------------------------------------- |
| accounts by segment | You route enterprise and mid-market differently |
| titles by seniority | VPs and directors get different plays           |
| signal by source    | You want to know which signal found the account |
| output by owner     | You are sending tasks to Salesforce             |
| failed rows         | You need a human review queue                   |

## Keep visualization close to the workflow

Recommended folder shape:

```txt theme={null}
workflows/
  weekly-new-accounts.play.ts
  input/accounts.csv
  output/accounts-enriched.csv
  output/accounts-summary.csv
```

The workflow creates the enriched list. The summary tells your team what changed.
