plotly.io.read_json 5.x doesn't work for graphs created with plotly>=6 #5297
Description
Steps to reproduce:
- create an environemnt with plotly==6.2.0 + numpy
- run this code (purely random plot), note the
write_jsonat the end
import numpy as np
# Generate random data
np.random.seed(42) # for reproducibility
random_x = np.random.rand(100) * 10 # 100 random numbers between 0 and 10
random_y = np.random.rand(100) * 10 # 100 random numbers between 0 and 10
# Create a scatter trace
scatter_trace = go.Scatter(
x=random_x,
y=random_y,
mode='markers', # Display markers for each data point
marker=dict(size=8, color='blue', opacity=0.7) # Customize marker appearance
)
# Create a Figure object and add the trace
fig = go.Figure(data=[scatter_trace])
# Update layout (optional)
fig.update_layout(
title='Random Scatter Plot (go.Figure)',
xaxis_title='X-axis',
yaxis_title='Y-axis'
)
# Display the plot
fig.show()
fig.write_json("test1.json")
- create a second environment with plotly<6.0.0 (5.9.0 in my example).
- run this code
from plotly.io import read_json
content = read_json("test1.json")
# content = read_json("test1.json", skip_invalid="True")
content.show()
- observe the next error:
Invalid value of type 'builtins.dict' received for the 'x' property of scatter

The 'x' property is an array that may be specified as a tuple,
list, numpy array, or pandas Series
Basically, figures saved with Plotly 6.x are not read back correctly when using Plotly 5.x. I am not if this is how it's supposed to be or not.
If I try content = read_json("test1.json", skip_invalid="True") it doesn't produce an error but the plot is completely wrong.
I would love any feedback on this, thanks in advance.
