What does pseudo-immutable mean?

So we create instance of DataModel once and then we perform operation like filtering, projection of columns, sorting etc. Everytime an operation is performed a new instance of DataModel is returned. Hence its immutable. But under the hood there is only one copy of data resides in the system shared by all instance of DataModel, for every operation we just record a formula and save it on DataModel instance. The data for that particular instance is computed on demand based on the formula. Its not a pure immutability by definition. Hence pseudo-immutable.

However, every operation does not support formula storing. Operation like joining, grouping creates new data.

We are updating the docs rapidly. All this info would be on the docs soon.

That's quite an interesting mix of HTML and SVG. Cool stuff. The website could be a bit more responsive. The charts are overlapping if I make the browser narrower.

Seems to work properly if you inspect it at common breakpoints. Love the cross-connectivity between charts.

How do you plan to support the team and project, financially, over the long haul?

We intend to be an open-core company, and monetize support and tools around the product.

Cool. You might consider describing Muze as a project rather than a product. E.g., On the homepage: Our first product, Muze... -> Our first project, Muze....

Is there a plan to create a version that generate the graphs and manage all the filtering on the server side instead of having all the data in the browser?

This will be very helpful for cases that uses large datasets...

I built visualization using dc.js, and working with large datasets was the biggest pain point for me.

We had plans to move DataModel (manages all data ops) to serverside. We even have a half baked DataModel in Scala which we thought we would do it once we understand some usecase. But currently we have put it on hold.

We would love to know your - use case - number of data points - ops on data on serverside
