| Thanks for input, but do You mind being a bit more specific about the following: - would You actually be interested to buy this service? - what sort of visualizations do You actually make? Do they need to be interactive? SVG? Size? How do You use them? - what exactly do You do with data before its plotted except selecting columns? Is there aggregation or any kind of processing? - how often is this actually used because You say 'sometimes every few months', does it mean its like a quarterly report? - what other well established tools have You used other than Excel? - how big is Your largest data? Size, rows, columns - if it applies with small amount of megabytes, is there a reason beside simplicity why You can't use PivotChart in Excel? Or Excel in general? Or R/Python to generate it? I am data scientist who regularly plots quite large data sets, and I like speed :) Its totally doable to build a service that You can run locally, load a CSV, read like 1% of data, play with it.. when you get what You want, load rest and wait a bit and get the visualization You want. But depending on visualization requirements there may be many paths solutions. |
