## Recipe Objective

Make 3D isosurf plots using plotly.

Isosurf plot these are used to extract the surfaces of a constant i.e "w" from a function of the form of "w=f(x,y,z)". It is the plot which equivalent to 3D contour plot. The data which is generated from these types of plots can be defined as a formula or loaded from a file.

## Step 1 - Import libraries

``` import plotly.graph_objects as go ```

## Step 2 - Take Sample Data

``` x = [1,1,1,1,2,2,2,2] y = [1,2,1,2,1,2,1,2] z = [1,1,2,2,1,2,1,2] value = [1,2,3,4,5,6,7,8] ```

## Step 3 - Plot graph ``` fig= go.Figure(data=go.Isosurface( x=x, y=y, z=z, value=value, isomin=4, isomax=8, )) fig.show() ```
