hello dears hope all is fine. would you please your support. at work we're using excel, how i do data visualization using charts and dashboard and ability to present reports on powerpoint? any materials / tips let me use excel as advanced like; power query, power pivot and visualization / charts excellent with jaws? On the other hand, I appreciate your support by suggesting courses for data analytics / data science using python for the visually impaired or general one could depend on it in my study. thanks very much

data analytics support
by Ibraam Wahib June 27, 2025

June 27, 2025

hello dears hope all is fine. Could you please, any recommendation for courses / books help us blind people to go deeper in data analytics in business. I don't recommend sonification tools, I believe it's not practical in business life for us. Also, any progress in jupyter accessibility? Do you suggest another way for Colab to improve using it or a similar website could help more in practice and could be used at work later? totally recommend a local method if available. From your perspective as a data Analyst or scientist which extensions should be installed, also recommended configurations for VS Code. Last point, could we use iPython in vs code if there is no solution for jupyter? Hopefully you share even recorded sessions could help me in this journey. thanks

Live stream: So how accessible are (Jupyter) notebooks for screen reader users?
by Tony Fast June 24, 2024

June 24, 2024

cross posting an event from zersiax on the jupyter discourse <https://discourse.jupyter.org/t/stream-so-how-accessible-are-jupyter-notebo…> happening tomorrow 6/25 on twitch <https://twitch.tv/ic_null> and youtube <https://youtube.com/@blindlyCoding> @ 3pm pst. message reposted below Hi all, Accessibility is one of those topics that is often ignored until it’s too late, at times deliberately, and at other times completely by accident. Unfortunately, the consequences of this are often far greater than most people realize; an inaccessible tool/platform can get companies sued, can get people fired (if their current employer adopts these tools), and can make huge portions of a target audience feel discriminated against and excluded. Notebooks, either built on Jupyter Notebooks, Google Colab, VS Code and what have you, are becoming more and more of a staple within various fields, be it AI, Machine Learning, Datascience, programming education and more. So how accessible ARE these tools, at present? Hi! I’m a fully blind (no sight, no monitor, no nothing) developer and accessibility auditor that likes to create this kind of content, and this is exactly the question I aim to answer in the coming (few) stream(s). Tomorrow at 3 PM EST (noon PST, 8 PM BST, 9 PM CEST), I will hop onto twitch <https://twitch.tv/ic_null> and Youtube <https://youtube.com/@blindlyCoding> in order to start answering this question. We’ll look at Jupyter Notebooks first and foremost, bring in resources the community have created over the years to talk about notebooks in general and their accessibility and talk about the notebooks UI from both a web developer as well as an accessibility expert’s point of view. Along the way, topics like " how would you represent data for a screen reader user?" and “if there are accessibility issues, how can a screenreader user best work around them?” will come up as well. There’s a huge lot to cover, so we may have to split this across several streams but for now, I hope i’ll be seeing some of you there tomorrow.

Re: Dash vs. Streamlit for GUI Development for a Data Science Project!

Marvin , you can: pip install streamlit Or if you're using Anaconda, you can try: conda install -c conda-forge streamlit The same can be done with Dash. Cheers, K From: hunkinmarvin5(a)gmail.com <hunkinmarvin5(a)gmail.com> Sent: Wednesday, May 22, 2024 7:05 AM To: 'Khalid K' <kaak42(a)outlook.com> Subject: RE: [data-science]Dash vs. Streamlit for GUI Development for a Data Science Project! Hi using jaws 2024. Using visual studio code, python 3.12 and github latest desktop version. Have not used Streamlit. And so a tutorial how to use this would be great and maybe a sampleproject. So then I could then see how accessible it is with a screen reader. So where do I download this and is it a pip install like on the terminal or is it a msi or exe file for windows 11. Have windows 11 pro 64 bit on a hp pavilion 15.6 inch laptop. Running jaws 2024, nvda 2024.1. Marvin from Adelaide, Australia..

Hi data scientists, I hope this message finds you well. I want to gather some insights on using Dash or Streamlit for GUI development. Specifically, I'm interested in the following: 1. Ease of Use with Screen Readers: Has anyone used Dash or Streamlit with a screen reader? Which one is more accessible and user-friendly? 2. Learning Curve: Which tool requires less time to learn and implement effectively? I have a few sighted friends who speak highly of Streamlit, mentioning its simplicity and ease of deployment -they don't use screen-readers though! My goal is to develop a GUI interface that can: Generate graphs Allow selection from a list of cryptocurrencies Provide scenarios like predicting next month's prices if I sell Load results and graphs quickly upon selection Your experiences with either tool would be greatly appreciated. Cheers, Khalid

OCR Tools
by Nikhil Vohra April 20, 2024

April 20, 2024

Dear all, I am trying to find a simple OCR tool to run locally. I came across Tesseract <https://tesseract-ocr.github.io/>, and I was wondering if anyone has experience using it, thoughts about it, or suggestions for OCR in general. Note: NVDA has built-in OCR (triggered with NVDA+R), but this only works for the current navigator object; I am trying to find a tool that works for entire documents. Thanks, Nikhil

Inquiry on Weka Accessibility for VI Data Scientists
by Khalid K April 15, 2024

April 15, 2024

Hi Data Scientists, I'd like to inquire about the accessibility of Weka (https://ml.cms.waikato.ac.nz/weka/) when using a screen reader. Does anyone have experience with its usability? Additionally, I'm curious to know whether it's essential to use Weka, or if similar productivity could be achieved using Python and libraries like Pandas, Seaborn, and scikit-learn. I look forward to any ideas or suggestions you have for enhancing productivity for data science with screen-readers. Kind regards, Khalid

Sonification.
by Gabriele Battaglia April 8, 2024

April 8, 2024

Hi guys. My first question has to do with a subject I care a lot, sonification. I tried astronify but I'm not very happy with it. In my opinion it lacks many things like stereo capability, using different waveforms, sonify more than 1 serie of data at the same time and a usless complex grammar. I would like to try something more complete and maybe easier to use. Do you know something like that, to import as a python library? Thanks.
