data visualization

by Ibraam Wahib

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

Re: data analytics support

by Ibraam Wahib

Hi patric thanks for your advice. i think Data Science at the Command Line is not easy for me. So, I will depend on the second one. Yes, I agree with you about AI. could i know which vs code extensions help me in data analysis? Hope, I find live or even recorded courses / workshops like yours. Wish I could read from experts here who really work in the data analytics / data science business field. thanks On Tue, Jun 10, 2025 at 7:51 PM Patrick Smyth <patrick(a)iotaschool.com> wrote: > Hi Ibraam, > > I'm a little out of the blind data science loop lately. > > Generally, I agree with you about sonification, with maybe some exceptions > a screen reader workflow will be more reliable.

Re: data analytics support

by Patrick Smyth

Hi Ibraam, I'm a little out of the blind data science loop lately. Generally, I agree with you about sonification, with maybe some exceptions a screen reader workflow will be more reliable. I also think a command line approach will generally be more stable right now, there's been a noticable jump in accessibility for notebooks but it may never be first-class. Have you seen the book Data Science at the Command Line? I link directly to the HTML version below. https://jeroenjanssens.com/dsatcl/ I might also take a look at Python for Data Analysis (also linking to the full free HTML version): https://wesmckinney.com/book/ Nowadays, if part of the book isn't accessible, you can try uploading a screenshot of your screen to Claude or OpenAI and they do a good job of telling you what's on there. This can also be helpful if you're having trouble parsing something in the book, you can upload the screenshot with a question. Generally, I would work on these things: - Statistics skills - Python skills - UNIX skills So if you're having trouble finding books or resources look for sub-skills in those areas and search for those. I do find that AI has been good to suggest high-level areas to pursue like this, not sure how much you're using these tools or if they're available to you? I forwarded your email to a couple folks as well just in case you hear back (you may not). Feel free to ask more questions, it's a tough road for us. Also if anyone else has thoughts or support jump in.

data analytics support

by Ibraam Wahib

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

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.

y'all, khalid and i have a wildly successful time doing data science work to create nonvisual heatmaps. i've annotated the stream with different sections <https://youtube.com/live/uF9VpP-mrSE> and created a notebook with the code and tables <https://tonyfast.github.io/tonyfast/draft/tonyfast/tonyfast/tonyfast/xxiv/2…> we explored during the event. hopefully y'all enjoy content like this and would like to see more. please let me know! best, tony

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

by Khalid K

Hey Patrick, Thank you for sharing this information about Streamlit and its approach to accessibility. It’s helpful to see that they have some considerations in place, but it’s a bit concerning that there hasn’t been a response from the Streamlit team since June 2021 on this topic. I’ll explore different options for the GUI in this project. If I decide to try Streamlit, I’ll make sure to share my experience with the group. A friend of mine, who is good at CSS, mentioned that he will use Flask for the GUI. This might be a faster and easier option to implement while meeting the requirement! Congratulations on the new job!

Hey Khalid, I'd try looking at Streamlet, I found this comment that suggests they do actually think about accessibility: ``` Thanks for the question. We haven’t done an official accessibility assessment. That said, we write our frontend code with accessibility in mind, using a widget component library 31 that is accessible, looking at contrast ratios when designing, etc. But we’re aware this is by all means not enough! That’s why we have a roadmap item to officially assess accessibility and address issues that arise. It’s important to note we don’t control user themes, plotting libraries, and custom components, and a lot of the accessibility of actual apps will fall on users who are writing these apps. --- That's from here: https://discuss.streamlit.io/t/508-compliance-for-streamlit/13579/2 Khalid, I owe you an email, apologies.

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.
