Run instruction appears to be incorrect

[jeff303]

In README.md, the instructions say to execute this to render the diagrams: node run build

However, at least on my system, this doesn't work.

node run build
node:internal/modules/cjs/loader:928
  throw err;
  ^

Error: Cannot find module '.../run'
    at Function.Module._resolveFilename (node:internal/modules/cjs/loader:925:15)
    at Function.Module._load (node:internal/modules/cjs/loader:769:27)

    at node:internal/main/run_main_module:17:47 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

However, npm run build works:

npm run build

Run instructions also don't work on my end. However, it's able to generate a README & crashes when generating the .svg file. Seems to be the same for npm run build

Output for node build run
