Publish latest commit to NPM
A fix was implemented in the most recent commit #b0ca825 that is not published to NPM, making the package not work with new versions of Sequelize.
Can you please publish the changes so installing it via NPM works properly?
Error: Cannot convert undefined or null to object
Just setup sequelize-erd with this line in my package.json sequelize-erd --source ./app/models/ --destination ./erd.svg
and get this error when I try a npm run erd

Error: Right-hand side of 'instanceof' is not callable
Issue
Occasionally for some reason Sequelize will provide a columnType
of a string representing the type of column.
In sequelize 3 using postgres, the column type of inet
will represent this.
Fixed in: #3
Error: Cannot find module 'sequelize'
I installed the package and added it to my package.json scripts.

thoughts?
Viz returns a Promise instead of a string
Hi,
Nice work!
In the API documentation there is a missing await
keyword because Viz.js returns a Promise in renderString
(wiki)
API example incomplete
Your API example is incomplete. It doesn't have the require('sequelize')
and where does sequelizeErd
come from?
const db = new Sequelize();
// Import DB models here
const svg = sequelizeErd({ source: db });
writeFileSync('./erd.svg', svg);
// Writes erd.svg to local path with SVG file from your Sequelize models
