# bytesagain-data-analytics

Terminal data analysis toolkit for CSV files. Compute statistical summaries, correlation matrices, top value rankings, trend charts, data quality reports, and pivot tables — no Python data science libraries required.

## Usage

```

- `correlate` — Pearson correlation matrix across all numeric columns
- `top` — Rank top 15 values in any column with percentage and bar chart
- `trend` — ASCII line chart showing value trend over rows with direction indicator
- `clean` — Data quality report: null counts, low cardinality, coverage per column
- `pivot` — Group by a category column and aggregate a numeric column

## Examples

```bash
bytesagain-data-analytics describe sales.csv
bytesagain-data-analytics correlate metrics.csv
bytesagain-data-analytics top customers.csv country
bytesagain-data-analytics trend revenue.csv amount
bytesagain-data-analytics clean user-data.csv
bytesagain-data-analytics pivot orders.csv category revenue
```
