Are donut charts memory efficient?

Hi!

I’ve added the following donut chart in my app:

dmc.Group(
  children = [
      html.Div(
          
          style = {
              "margin-left":"28px",
              "margin-top": "12px",
          },
          children = [
              # Interval component for triggering updates every second.
              dcc.Interval(id='donutchart-neighbors-progress-interval', interval=1000),
              dmc.Box(
                  [
                      dmc.DonutChart(
                          id="donutchart-neighbors-progress",
                          size = 130,
                          data=[
                              {"name": "Current Neighbor", "value": 0, "color": "grape"},
                              {"name": "Total Neighbors", "value": 0, "color": "gray.7"},
                          ],
                          chartLabel=f"",
                          fw=700,
                          thickness=10,
                          withTooltip=False,
                          tooltipDataSource="segment",
                          pieProps={"isAnimationActive": False},
                      ),
                  ]
              )
          ],
      ), 
  ],
)

this is its calllback function:

@callback(
    [Output('donutchart-neighbors-progress', 'data'),
     Output('donutchart-neighbors-progress', 'chartLabel')],
     Input('donutchart-neighbors-progress-interval', 'n_intervals'),
     prevent_initial_call=True
)
def progress_neighbors(n_intervals):
    
    current_tx_idx = self.get_state('current_transaction_idx') + 1
    total_neighbors_txs = self.get_state('current_nr_txs')

    updated_data = [
        {"name": "Current Neighbor", "value": current_tx_idx, "color": "grape"},
        {"name": "Total Neighbors", "value": total_neighbors_txs - current_tx_idx, "color": "gray.7"},
    ]
    chart_label = f"{current_tx_idx}/{total_neighbors_txs}"
  
    return updated_data, chart_label

i’ve also added a 2nd donut chart with the same logic. The variables in the scripts are integers. The lists are not long. Yet, memory consumption has increased significantly.
