apio graph fails - cant find 'dot'

[pm100]

Windows, fresh install of everything; 'apio upload ' works fine

PS C:\work\nandland\go-board\Blinky> apio graph
yosys -f verilog -p "show -format dot -colors 1 -prefix hardware Test" -q Blinky.v
dot -Tsvg hardware.dot -o hardware.svg
'dot' is not recognized as an internal or external command,

Thanks @pm100. 'graph' is a new command that was added recently. As a woraround, you can install the graphviz package manually as explain at https://graphviz.org/download/ . This should provide the 'dot' command.

@Obijuan, the dot command used to convert the .dot file that yosys generates to .svg. Any idea how to have it installed automatically?

yosys -f verilog -p "show -format dot -colors 1 -prefix hardware main" -q fifo_tx.v i2s_rx.v i2s_test_pattern.v i2s_timing.v main.v meta_stability.v queue.v queue_pusher.v register.v reset_gen.v sine_gen.v status_leds.v

dot -Tsvg hardware.dot -o hardware.svg

EDIT: a portable viewer of .dot file will also be useful, if there is one.

yes , installing grpahviz solved my problem, Maybe just a doc update needed
