Periodic Table

See pymatviz/ptable/ptable_matplotlib.py and pymatviz/ptable/ptable_plotly.py. matplotlib supports heatmaps, heatmap ratios, heatmap splits (multiple values per element), histograms, scatter plots and line plots. plotly currently only supports heatmaps (PRs to port over other matplotlib ptable variants to plotly are very welcome!). The plotly heatmap supports displaying additional data on hover or full interactivity through Dash.

Structure

See pymatviz/structure_viz/(mpl|plotly).py. Currently structure plotting is only supported with matplotlib in 2d. 3d interactive plots (probably with plotly) are on the road map.
