Learn by Experimenting
This is a safe playground for learning! Try changing:
- • Colors: Modify color values to see different palettes
- • Numbers: Adjust sizes, positions, or data ranges
- • Labels: Update titles, axis names, or legends
Edit the code, run it, then open the full data visualization tool to continue with your own dataset.
1. Quick Comparison Table
| Feature | Julius AI | Plotivy |
|---|---|---|
| Primary Focus | Conversational data analysis | Publication-ready figures |
| Code Output | Hidden behind chat interface | Full Python code, editable |
| Code Editing | Cannot edit generated code | Monaco editor + re-run |
| Export Formats | PNG, basic resolution | PNG/SVG/PDF, 300-1200 DPI |
| Data Sources | CSV, Excel, Google Sheets | CSV, Excel upload |
| Journal Templates | None | Nature, Science, ACS, IEEE |
| Conversational AI | Excellent | Prompt-based generation |
| Statistical Tests | Built-in via conversation | Via generated Python code |
2. Data Privacy & Security
Julius AI
- - Data uploaded to Julius servers
- - Cloud-based processing only
- - SOC 2 compliance claimed
- - Data retention policies vary by plan
Plotivy
- Only AI prompt descriptions sent externally
- Raw data never leaves your browser
- Code execution is sandboxed
- Safe for pre-publication data
3. Code Output & Editability
Why editable code matters for researchers
- Reproducibility: Colleagues can run your exact code to reproduce figures.
- Iteration: Change a color, axis range, or annotation without re-prompting.
- Learning: Reading and modifying real Python code builds skills faster than chat.
- Version control: Code can be committed to Git alongside your manuscript.
Julius generates code internally but does not expose it for editing. Plotivy gives you full control over the generated matplotlib/plotly code.

Scatterplot
Displays values for two variables as points on a Cartesian coordinate system.
Sample code / prompt
import matplotlib.pyplot as plt
import numpy as np
from scipy import stats
import pandas as pd
# Generate sample data
np.random.seed(42)
n_samples = 200
height = np.random.normal(170, 8, n_samples)
weight = height * 0.6 + np.random.normal(0, 8, n_samples) - 50.png&w=1920&q=75)
Box and Whisker Plot
Displays data distribution using quartiles, median, and outliers in a standardized format.
Sample code / prompt
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
from scipy import stats
# Generate gene expression data for 4 genotypes
np.random.seed(42)
genotypes = ['WT', 'KO1', 'KO2', 'Mutant']
n_per_group = 20
Heatmap
Represents data values as colors in a two-dimensional matrix format.
Sample code / prompt
import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd
import numpy as np
# Create correlation matrix for financial metrics
metrics = ['Revenue', 'Profit', 'Expenses', 'ROI', 'Customers', 'AOV', 'Marketing', 'Employees']
correlation_data = np.array([
[1.00, 0.85, -0.45, 0.72, 0.88, 0.65, 0.72, 0.55],
[0.85, 1.00, -0.78, 0.92, 0.75, 0.58, 0.63, 0.48],
Error Bars
Graphical representations of the variability of data indicating error or uncertainty in measurements.
Sample code / prompt
import numpy as np
import matplotlib.pyplot as plt
from scipy import stats
# Generate bacterial growth data with replicates
np.random.seed(42)
time_points = np.array([0, 4, 8, 12, 18, 24])
mean_values = np.array([10, 25, 80, 250, 600, 800])
# Generate 5 replicates per time point with noise
Violin Plot
Combines box plots with kernel density to show distribution shape across groups.
Sample code / prompt

import seaborn as sns
import pandas as pd
import numpy as np
from scipy.stats import f_oneway
# Generate exam score data for 3 groups
np.random.seed(42)
control = np.random.normal(72, 12, 50)
treatment_a = np.random.normal(78, 10, 50)
Histogram
Displays the distribution of numerical data by grouping values into bins.
Sample code / prompt
