Look at diagrams.net (formerly draw.io). It is gratis (free of cost). I use it intensively as a software engineer to architect and design different workflows.
There is also a desktop app for the same web tool.
Besides gdal2tiles, you could use vips. Details are in here: https://stackoverflow.com/a/51852934/10168903
If you want a GUI based solution, you could use Photoshop or Microsoft Image Composite Editor. You would need a plugin from zoomable.ca though.
Before you try MS Visio, have a look at yEd. It's free, works on Windows as well and can also draw flowcharts.
You can adjust the colors etc. to make it look closer to Visio.
Downside: I needed to get used to its usability. It doesn't behave like I expected it would. Usually I accidentally draw a lot of more boxes than needed.
You can use Syncfusion's Flutter DataGrid which has lot of features such as,
Cell interactions callbacks
You can go through Feature Tour to know about all features and go through UG.
It sounds to me like you want visidata.
VisiData is an interactive multitool for tabular data. It combines the clarity of a spreadsheet, the efficiency of the terminal, and the power of Python, into a lightweight utility which can handle millions of rows with ease.
I can not comment so I apologize for 'answering', but it seems to me you need error correction or even RR retries rather than guessing disguised as statistics. So for this you'd need a reader/adapter that dumps the NAND while bypassing the controller. See for example: http://www.flash-extractor.com/manual/read_retry/step_by_step/.
Also if we compare C0 and ...

Diagram is a feature-rich JS component for visualizing, creating, and editing interactive diagrams like flow charts, organizational charts, mind maps, BPMN diagrams, and more. Its rich feature set includes built-in shapes, editing, serializing, exporting, printing, overview, data binding, and automatic layouts.
Herewith we have a created a sample to display ...
if your columns are strictly numeric, and ideally non-null, you can try Principal Components Analysis, PCA. That's one of the oldest techniques of multiimensional analysis.
Performing the PCA can be done in a single line of code. After all, it's a variant of a matrix factorization. If I remember correctly.
However, the interpretation of the components is ...
You should write a program processing those Excel files. Though many programming languages provide API to read data from Excel files, you still need to write code to open each file, traverse cells to read desired data, input all data into memory and store it in one data set object, usually use Python to convert a sheet into a dataframe with pandas. But using ...
TimelineSetter is a tool to create HTML timelines from spreadsheets of events.
You can use pyan.py to generate a call graph. See this stackoverflow question for details.
Usage: pyan.py FILENAME... [--dot|--tgf]
Analyse one or more Python source files and generate an approximate call graph
of the modules, classes and functions within them.
-h, --help show this help message and exit
--dot output ...
The image part requires some heavy lifting so I don't think anybody wrote software to do that -- it is certainly not impossible.
For the rest of the requirements, I think this answer (by me) offers the exact (and free) solution:
Been for many years an infrequent yEd user, I want to add draw.io to the list.
Here's the diagram from the question, created in a desktop version of draw.io and subsequently exported to a PNG (clickable):
By the magic of draw.io (on export, it allows to embed the original diagram in the file), you can open it in the online editor -- "File" => &...
Looks like this hasn't been touched in a while. My thoughts are based one key observation - misunderstanding of what a DFD is, by the original poster and all of the responses. A flowchart is not a DFD.
Fundamentally, a DFD has only a very few symbols:
A data store (any type) drawn as two parallel horizontal lines with the description of the type of data ...
