Matplotlib.pyplot with Django

Question

I’m trying to insert a graph through the matlib.pyplot library, but I can only upload it externally by inserting it into Jango. I want to insert it as a loaded image, that when receiving data from the database, it generates an image whenever it receives new data.

The current code looks like this: Views.py

def dashboard(request):
dados = Usuario.objects.all().order_by('-created_at')
x = [6, 7, 4]  # Base
y = [2, 6, 2]  # Altura

titulo = "Hello World"
eixox = "Eixo X"
eixoy = "Eixo Y"

grafico = plt.title(titulo)
grafico = plt.xlabel(eixox)
grafico = plt.ylabel(eixoy)
grafico = plt.plot(x, y)
grafico = plt.savefig('save.png', dpi=72)
return render(request, 'Usuario/dash.html', {'dados': dados, 'grafico': grafico})

I want to make a Dashboard with User data and that on top appear metrics on a certain attribute of the model, but here I am only tested with simple data and I had tested alone.

In Dash.html it looks like this:

{% extends 'base.html' %}
{% block title %} DashBoard {% endblock %}


 {% block content %}

 <div>
 <img src="save.png">
 </div>
 <h1 class="mb-5">DashBoard</h1>
<table class="table">
    <thead class="thead-dark">
        <tr>
        <th scope="col">Tipo Usuário</th>
        <th scope="col">Status Usuário</th>
        <th scope="col">Nome do Usuário</th>
        <th scope="col">Login</th>
        <th scope="col">Última Atualização</th>
        </tr>
    </thead>
    <tbody>
{% if messages %}
    <ul class="messages">
        {% for message in messages %}
            <li {% if message.tags %}class="alert alert-success" {% endif %}>{{ message }}</li>
        {% endfor %}
    </ul>
{%  endif %}
    {% for dados in dados %}
        <tr>
        <th scope="row">{{dados.Tipo_Usuario}} </th>
        <td>{{dados.Tipo_Status_Usuario}}</td>
        <td>{{dados.Nome_Usuario}}</td>
        <td>{{dados.Login_Usuario}}</td>
        <td>{{dados.updated_at}}</td>
        </tr>
    {% endfor %}
    </tbody>
</table>

{% endblock %}

Image saved but not shown in html

I’ve been at it for more than three days, I’ve looked at foreign forums and here too, but I can’t solve it with their solutions.
