"""The purpose of the Kickstarter Dashboard is to test if the claims regarding Bokeh as of Jan 2018 in the
[bokeh-dash-best-dashboard-framework](https://www.sicara.ai/blog/2018-01-30-bokeh-dash-best-dashboard-framework-python)
article holds for Panel and the HoloViews suite of tools as of Dec 2019.
The claims where
- Data in Bokeh becomes inconsistent
- Cannot link charts to dataframe
- Bokeh is slow for big datasets
- Interactions take a long time to develop
You can evaluate this dashboard and the code to make your personal evaluation of the above
statements.
My evaluation is
- the **first two statements does no longer hold**.
- The third is up for discussion. I would also like the Dashboard updates to be a bit faster. Maybe it's because I don't yet know how to implement this efficiently.
- The fourth I've also experienced
see this [discussion](https://discourse.holoviz.org/t/how-to-create-a-parameterized-dashboard-with-seperation-between-data-transforms-and-data-views/53/13).
I can see that I made a lot of mistakes because it takes time for me to understand how the api works.
There is a lot to I need to learn across the HoloViz suite of tools."""
