Glaciers explorer using Datashader¶
This notebook provides an annotated HoloViews+Panel implementation of a dashboard originally developed in Plotly+Dash for viewing data about the Earth's glaciers from the Open Global Glacier Model. To run it, first:
conda install -c pyviz pandas=0.24 param=1.9.0 panel=0.5.1 holoviews=1.12.2 geoviews=1.6.2 datashader=0.7.0
Next, save the data file as
data/oggm_glacier_explorer.csv (and gzip it if desired).
The dashboard can then be used here as a cell in the Jupyter notebook, or you can run it as a separate server using:
bokeh serve glaciers.ipynb --show
