Very nice job! Just one advice if you don't mind - CANVAS is way much faster for this purpose than SVG, check out https://www.wikibudgets.org/w/svk/hlohovec/2016/ (and Drag&Drop editor https://www.wikibudgets.org/sankey/)


those are some cool looking diagrams... Something to aim for I have been thinking about using canvas because like you point out, its faster. However I had not worked at all with the canvas and new something about d3.js and svg. d3.js allowed me to use some dragging / events, which I could not have build myself when i started out with this project. That was simply what tipped me in to going with svg. To late to change now...And although there are times when speed is an issue when using the map, its got more to do with some inefficient programming from me.


Hello, you might want to work on the Call to Action button/link. For me there was no clear indication where I should click to try it out.

Also, the text and logo at the left don't seem to be centered in the left "region". It seems too close to the screenshot to me.

In the program itself, this http://i.imgur.com/I6oHv7c.png seems really confusing. The pointer makes it look like I can actually drag it, but that's not possible.


great feedback, I get now how the pointer can be confusing, will change that very soon. I will also take a look at a clearer 'to the map!' I have had more feedback about this, and made some changes, but apparently not good enough. Thanks!


I have been using yEd (https://www.yworks.com/products/yed) for many years on the desktop and I've been looking for a decent online alternative for almost as long.

This looks very promising, the only thing I miss is the ability to export as an image.

Excellent work!


Thanks a lot! I am working on selecting a print region to export a map as pdf. Will look into adding a feature to export as an image. What for you would be the benefit of of exporting as image instead of as pdf ?


PDF is great if you want to print but nothing beats the simplicity of a PNG for displaying on a web page or inserting into a Word document.


have you seen mindmup?


Cool project!

I usually use Draw.io [1] for making a flowchart and diagramming. Before that, I used Microsoft Visio. But, online tools help me more because we can synchronize our works in the cloud.

I was just looking for something exactly like this a few days ago -- to help me plan out a large new project. I ultimately ended up doing everything on paper, but I'm going to try it out anyways. Hoping for the best!


This is great! I believe encryption is a must have if you want people to ideate. Both group level and personal. Personal can be free and Group can be monetized maybe?


Thanks for the feedback! What kind of encryption are you thinking about (don't really know much about the topic). Do you mean secure online storage of notes and maps you make ? Or actual encoding of stored maps or https ?


Definitely going to be trying this. It's almost exam time for me and I always make mind-maps to help visualize and drive concepts home.

Good job!


Thanks! hope it helps and good luck with the exams.


Nice project! Is there a snap to grid functionality? Being able to easily align a diagram is a must have for me.


Thanks. In the development-version there is snap to grid! Hopefully this will be online someday next week. It will let you choose the delta for the grid.


Great job! My current project involves a whole lot of SVG and I'm quite happy with the performance. I'm using the Snap svg library and some hard coded SVG. Perhaps d3.js is causing the dragging to slowdown? Have a look at SNAP.svg


Cool stuff. I'd have liked to see a signup box to leave my email.


Thanks for taking a look. can I ask what you expect after leaving your email ? Would you expect a newsletter about more features, new examples etc ?


Multiplayer support planned? Being able to collaborate with a tool like this is something I've looked for for a while.


Collaboration by saving and sharing maps / notes using github gist is something I plan to make pretty soon.

Collaboration as in simultaneously working on the same map in some form or the other is something I have been thinking about, but really have little idea about implementing yet.


So is this a sort of online alternative to MS Visio?


Well not exactly. It would be best described as a mix between MS one-note and MS Visio and Powerpoint (coming soon).


I don't get the logo :-/


Well, It's a buffalo breaking down your notes into manageable pieces.


Mmm... I'm not sure it works.


What would you suggest instead? I think it looks well designed and clean, and just as acceptable as any of the other myriad animal-based logos.


I'm not a graphic designer, so I can't tell you what would work, but as a potential customer I can tell you that one doesn't.
