Easiest way I've found to remove top triangle in view
# Correlation
df_corr = data.corr().round(1)
# Mask to matrix
mask = np.zeros_like(df_corr, dtype=bool)
mask[np.triu_indices_from(mask)] = True
# Viz
df_corr_viz = df_corr.mask(mask).dropna(how='all').dropna('columns', how='all')
fig = px.imshow(df_corr_viz, text_auto=True)
fig.show()

Deb. Here it goes the answer for the first of your questions.
Seaborn colormap that I was create, I want to create something similar in Plotly. How can I do that?
You can use of the built-in colorscales in Plotly, which can be set via the parameter colorscale in the Heatmap constructor. Also, you can set Plotly's theme to get rid of the ugly background
import plotly.io as pio
import plotly.express as px
import plotly.graph_objects as go
pio.templates.default = "plotly_white"
go.Heatmap(
z=corr.mask(mask),
x=corr.columns,
y=corr.columns,
colorscale=px.colors.diverging.RdBu,
zmin=-1,
zmax=1
)

Correlation Heatmap in Plotly - ๐ Plotly Python - Plotly Community Forum
March 11, 2021 - I have created a lower triangular correlation heatmap using Seaborn that I loved. Now trying to create the same using Plotly. Unfortunately, not being able to fine tune it like I did with Seaborn. names = ['U', 'V', 'W', 'X', 'Y', 'Z'] r = pd.DataFrame(index = names, columns = names) r['U'] = np.array([1.0, 0.53, 0.26, 0.63, 0.52, 0.65] ) r['V'] = np.array([0.53, 1.0, -0.17, 0.83, 1, 0.85]) r['W'] = np.array([0.26, -0.17, 1.0, 0.04, -0.15, 0.09]) r['X'] = np.array([0.63, 0.83, 0....

Plotly Heatmap - Tips, Tricks, and Examples" โ Kanaries
August 17, 2023 - A correlated heatmap is a type of heatmap that is often used to visualize the correlation matrix of a dataset. The correlation matrix is a table that shows the correlation coefficients between many variables. Each cell in the table shows the correlation between two variables. A correlation matrix is used to summarize data, as an input into a more advanced analysis, and as a diagnostic for advanced analyses. In Python, you can use the Plotly library to create a correlated heatmap...

How to generate heatmaps to correlate materials properties
We can observe the same trend of correlation coefficients as seen in Pandas. You can also generate the heatmap with coefficient values using the plotly.express module (usually imported as px).

Plotly - Heatmap
Heat Maps are innately self-explanatory. The darker the shade, the greater the quantity (the higher the value, the tighter the dispersion, etc.). Plotlys graph_objects module contains Heatmap() function. It needs x, y and z attributes.

Correlation plot with mask - ๐ Plotly Python - Plotly Community Forum
September 25, 2019 - Hi Community, is there a way to create in python a correlation graph (using pandas.DataFrame.corr) with a โmaskโ or some other option, so the output looks like the image below (created using seaborn) with the following code: mask = np.zeros_like(corr, dtype = np.bool) mask[np.triu_indices_from(mask)] = True cmap = sns.diverging_palette(220, 10, as_cmap = True) f, ax = plt.subplots(figsize=(30, 10)) ax = sns.heatmap(corr, mask = mask, cmap = cmap, vmax = 1,square = True, linewidths = .5, c...
