This creates some interesting technical challenges. We implemented a custom visualisation engine that efficiently displays only the data that fits the screen. In the same way, we also support applying functions such as low-pass filters, integrals, derivatives, etc.
Having a visual approach to analysing data is in our opinion still highly underrated. Common engineering tools such as Matlab or python+matplotlib scripts require you to reduce the number of samples yourself. And you end up with a plot that is not interactive: zooming, panning highlighting, adding a different signal are all cumbersome or impossible. Marple treats interactivity as a first class citizen.
We recently launched a beta version and we're currently looking for test users to try it out. If you sometimes need to visualise some data from a .csv file, python script, matlab script, simulation, ... you should give it a spin!
- Is there druid integration? Is this a replacement for druid?
- How does schema inference work?
- Can I do SQL queries?
- How is this better than superset?
Integrating into a larger enterprise data dictionary would be nice. Eg, amazon glue
This is really a big data visualization tool. There's a whole gigantic rich market there to capture. You seem to be looking at it from the perspective of csv files, which is a fresh take, I guess.
It's also unfortunately a very competitive space being worked on by folks with insanely deep pockets and hyper smart engineers: https://www.newgenapps.com/blog/10-big-data-visualization-to...
Still, a lot of what's out there is ungainly bloat ware meant for business logic data. If you target specific engineering/science verticals with clear use cases, it would compete.
Yet another great project supported by imec!
- on MacBook 13", when editing calculated signals the dialog is bigger than the screen and the dialog cannot be closed (and maybe some other parts of the interface are hidden) - maybe add a max width/height on the dialog and a scroll
- the license does not work on windows (but works on mac build)
- on mac the feedback button the application splits in 2 identical views, with the mouse cursor movements mirrored (and an error about creating a folder .../bugs)
I'd be very curious to hear about some of the tech stack design choices.
I'd be also interested to understand who's your target user.
If you are going after individual contributor, I'd spend quite some time figuring out good integration points (ie.: Notebooks), so you are better integrated in their workflow. I'd avoid going enterprise, because date warehouse and data visualization are well solved problem (both in SaaS and PaaS flavor). Source: I led data organization at mid/big companies.
Thank you for the info, we're still finding our position in the market. Figuring out the perfect use case and integration in a certain workflow will be key indeed!
