# Showcase
Exercises every method of the graph fluent builder API in a single coherent
graph, plus training tools, observation, and visualization.
```sh
cargo run --example showcase
```
## Builder methods exercised
`from`, `through`, `tag`, `using` (backward & forward refs), `split`, `merge`,
`also`, `map` (slices/each/over/batched), `loop_body` (for/while/until),
`gate`, `switch`, `fork`, `input`, `tag_group`, `build`
## Graph methods exercised
`forward`, `forward_multi`, `parameters`, `train`, `eval`, `set_training`, `reset_state`,
`detach_state`, `dot`, `tagged`, `flush`, `trend`, `enable_profiling`,
`flush_timings`, `timing_trend`
## Training tools exercised
Adam optimizer, CosineScheduler, mse_loss, clip_grad_norm,
save/load checkpoint, no_grad, observation, profiling, trends
