Hello Julian,
I have experience with D3.JS visualizations and interactive charts, I am also experienced with Kibana and ELK stack. I have worked with Python and I have experience with JavaScript as well.
I am writing this on a mobile device, so the thing I could notice with the current work in progress attached with your link is mainly the interactive part, that I have to move a slider and wait for the updates, I mean it could be made more interactive by clicking on the chart itself and having more options perhaps instead of horizontal bar graphs, for example pie charts that could have split levels depending on the type of data required.
Let’s talk about more details.
Thanks,
Ahmed
