Depending on your work environment, you could do fully custom BI proposals.

Custom BI Tools

For a PoC on BI Tools, go for Streamlit:

Streamlit PoC Post

Streamlit PyGWalker Rendered Map with locations…

Marketing Docs

Funnels with Streamlit

To build a BI Tools even more custom: with certain UI look and feel, you can try Flask

Flask and Real Time Data

Flask WebApp + WebSockets Real Time Temperature Connection working with the x300

Custom Plots for Reporting

Sample YFinance based reporting

To create interactivity, we have the well known plotly, but also ApexCharts and ChartJS.

Sample NodeJS x ApexChartJS Generator

Using NodeJS to generate ApexCharts

Both can be combined and create some cool graphs within SSGs, like in HUGO components and also provide interactivity via CSR.

You can potentially make embedable BI components that work on websites or just get the full power of web apps when designing these.

You could also use these skills when building funnels during your entrepreneurial journey:

PS Reflex has very cool funnels: https://reflex.dev/docs/library/graphing/charts/funnelchart/

You can also create a quick mermaidJS sankey of on boarding flows.
